Class 12 Science MCQ Test Online: Chapter Wise — Physics, Chemistry, Biology, Maths, English | CBSE 2026-27

master the new CBSE pattern online MCQ test 100 percent NCERT based chapter wise tests with competency based questions CBQ for board exam preparation

You just stepped into Class 12. The CBSE board exam is in February 2027 — roughly 8 months from now. You have five subjects, each with 12 to 16 chapters, and the new CBSE exam pattern says nearly 70% of your board paper will have MCQ or competency-based questions.

Most students start reading NCERT, make notes, and then realise a month before boards that they have never actually practised MCQs chapter-by-chapter. By then, it is too late to build the speed and accuracy that MCQs demand.

This blog covers CBSE chapter-wise MCQ tests for all five Class 12 Science subjects — Physics, Chemistry, Biology, Maths, and English — based on the CBSE 2026-27 syllabus. It also explains where you can start practising right now, for free, without downloading any app.

Why 70% of Your Class 12 Board Paper in 2027 is MCQ-Based

The 50-20-30 Rule — CBSE Exam Pattern 2026-27

Most students think MCQs are just those one-mark tick-the-box questions at the start of the paper. That is only part of the picture. The CBSE Class 12 exam pattern for 2026-27 follows what is called the 50-20-30 rule:

Component

Percentage

Question Types

Competency-Based Questions (CBQs)

50%

Case-based MCQs, Source-based MCQs, Assertion-Reasoning MCQs

Objective Questions (Standard MCQs)

20%

One-mark MCQs — pick the right option from four choices

Constructed Response (Written Answers)

30%

Short answer and long answer written questions

When you add CBQs (50%) and standard MCQs (20%) together, 70% of your Class 12 board paper has MCQ elements. If you have only been practising written answers, you are going into the exam underprepared for more than half the paper.

What Types of MCQs Will You Actually Face?

  • Standard MCQ — One question, four options. Pick the correct one. Direct and straightforward.
  • Case-Based MCQ — A short paragraph or situation is given. Then 4 to 5 MCQs follow based on it. Common in Chemistry and Physics.
  • Source-Based MCQ — A graph, data table, or extract is given. You answer MCQs based on it. Common in Biology and Physics.
  • Assertion-Reasoning MCQ — Two statements: Assertion (A) and Reason (R). You decide which combination is correct. This type is specifically introduced in Biology for the 2026-27 session.

Why Reading NCERT Alone is Not Enough

  • Students know the concept but freeze when they see four similar-looking options.
  • MCQs need to be answered in 60 to 90 seconds each — speed comes from practice, not from re-reading.
  • Easy one-mark questions are lost in Chemistry and Biology because option-elimination was never practised.
  • Case-based MCQs need the skill of reading a situation and extracting facts under time pressure.

MCQ accuracy is a skill. It comes from practice, not from reading the chapter one more time.

Boards and Entrance Exams – One Practice, Double Benefit

If you are targeting JEE Main 2027 or NEET UG 2027 alongside your boards, MCQ practice does two things at once. Both JEE Main 2027 and NEET UG 2027 are 100% MCQ-based. Every Physics, Chemistry, and Biology MCQ you practise for your boards also builds your entrance exam readiness. You do not need a separate MCQ bank for boards and entrance exams — a good chapter-wise portal handles both.

CBSE board exams for the 2026-27 session are expected in February–March 2027. Students entering Class 12 in June 2026 have approximately 8 to 9 months to build strong MCQ accuracy. The best time to start is right now — not October.

Key Changes in CBSE 2026-27 Every Class 12 Student Should Know

NEP 2020 Alignment — What Actually Changed

CBSE has updated the Class 12 syllabus and exam pattern in line with the National Education Policy 2020. The key shift is this: questions now test how well you can apply a concept to a new situation — not just whether you can recall a definition. This is exactly why MCQ practice matters more than memorisation.

  • Case studies and situational MCQs test application of knowledge, not rote learning.
  • NCERT is still your base, but you need to understand every line, not just remember it.
  • HOTS (Higher Order Thinking Skills) questions are built directly into the MCQ format.

Two Board Exam Sessions in 2026-27

  • Main exam — February 2027 (primary session for all students)
  • Optional second attempt — May 2027 (for improvement only)
  • Your best score from the two attempts will count as the final result.

This policy reduces some pressure but should not reduce preparation. The February 2027 exam is still the one most students take seriously, and 8 months of consistent chapter-wise MCQ practice is what makes the difference.

Passing Criteria — The 33% Rule

Students must score at least 33% in theory AND 33% in practicals separately to pass. A strong theory score cannot compensate for weak practicals. Both need consistent attention throughout the year.

Class 12 Physics MCQ — Chapter Wise with Unit-Wise Marks — CBSE 2026-27

Why Physics MCQs Are Different from Other Subjects

Physics MCQs in Class 12 combine numerical reasoning and concept application. Four options are often very close — two look correct if you have only read the chapter casually.

Speed matters: in a 3-hour board paper, MCQs need to go fast, and for JEE Main 2027, Physics MCQ accuracy at the chapter level is what separates good scores from great ones.

Which Physics Chapters Get the Most MCQs?

Current Electricity (Ch 3), Ray Optics (Ch 9), and Electrostatics (Ch 1 & 2) together carry the highest MCQ load in both CBSE boards and JEE Main 2027. Start your chapter-wise Physics MCQ practice here first.

For Electromagnetic Induction and Alternating Current, MCQs are formula-based and repeat in a predictable pattern — a few hours of focused practice can lock in 4 to 6 marks. Semiconductor Electronics (Ch 14) carries only 7 marks but shows up reliably in the MCQ section every year. Do not skip it.

For JEE Main 2027 Students

The portal at Aspirations Institute Test Portal covers both Class 11 and Class 12 Physics chapters. Students targeting JEE Main 2027 can practise all 14 Class 12 Physics chapters chapter-wise on the portal and then extend the same practice to Class 11 chapters. You do not need a separate platform for boards and JEE.

Class 12 Chemistry MCQ — Chapter Wise with Unit-Wise Marks — CBSE 2026-27

Why Chemistry MCQs Are the Trickiest in Class 12

Chemistry MCQs in Class 12 come in three types, and each needs a different approach:

  • Physical Chemistry MCQs — Formula-based. Apply a value, use the formula, pick the right answer. Practise these with actual calculations.
  • Organic Chemistry MCQs — Product and mechanism based. The wrong options are chemically plausible, not obviously wrong. These are the hardest to guess without practice.
  • Inorganic Chemistry MCQs — Memory and elimination based. The more you read and revise, the faster you eliminate wrong options.

Electrochemistry and Coordination Compounds carry the highest marks in Chemistry and are consistently high-MCQ-load in both CBSE boards and NEET UG 2027.

Tips for Class 12 Chemistry MCQ Practice

  1. Organic Chemistry (Units 6 to 9): Practise product prediction MCQs chapter-wise. Do not memorise reactions — understand the mechanism. Knowing why a substitution happens instead of elimination helps you answer questions you have never seen before.
  1. Coordination Compounds (Unit 5): IUPAC naming and isomerism MCQs repeat every year. One focused session on this chapter gives very high returns.
  1. Electrochemistry (Unit 2): This chapter has the highest marks in Chemistry — 9 marks. MCQs involve Nernst equation, conductivity, and cell EMF. These are calculation-based — practise them with numbers, not just theory reading.

For NEET UG 2027 Students

NEET Chemistry has 45 questions (180 marks) from both Class 11 and Class 12 chapters. Electrochemistry, Biomolecules, Coordination Compounds, and the entire Organic Chemistry section (Units 6 to 9) overlap directly with the NEET syllabus. Chemistry MCQ practice on the portal covers your board prep and NEET prep at the same time.

Class 12 Biology MCQ — Chapter Wise with NEET UG 2027 Angle — CBSE 2026-27

Why Biology MCQ Practice is Different

Biology MCQs in Class 12 are almost entirely NCERT-based. Every sentence in your NCERT textbook can become an MCQ option. The wrong answers are not random — they are pulled from neighbouring paragraphs, similar-looking terms, or concepts from related chapters.

For the CBSE 2026-27 session, Assertion-Reasoning MCQs are specifically introduced in Biology. This is a new MCQ format, and many students are not used to it. Getting comfortable with this format requires dedicated chapter-wise practice — reading the chapter alone will not help.

If you are targeting NEET UG 2027, here is a number that matters: Biology carries 360 out of 720 marks in NEET. Class 12 Biology covers approximately 50% of the NEET Biology syllabus. Starting chapter-wise MCQ practice now in June 2026 is the most efficient use of your time.

What Are Assertion-Reasoning MCQs in Biology?

An Assertion-Reasoning MCQ gives you two statements:

  • Assertion (A): A factual statement about a concept
  • Reason (R): A statement that may or may not explain the Assertion.

You then pick from four options:

  1. Both A and R are true, and R is the correct explanation of A
  2. Both A and R are true, but R is NOT the correct explanation of A
  3. A is true, but R is false
  4. A is false, but R is true.

You cannot guess your way through these. You need to understand the concept clearly — not just know the definition. Practising A-R MCQs chapter-wise before the February 2027 boards is the only reliable way to get comfortable with this format.

Which Biology Chapters to Prioritise for MCQ Practice

  • Highest priority (boards + NEET both): Genetics — Ch 5 (Principles of Inheritance) and Ch 6 (Molecular Basis of Inheritance). These two chapters together carry the highest MCQ density in Class 12 Biology. They also appear heavily in NEET UG 2027.
  • Second priority: Human Reproduction (Ch 3), Biotechnology (Ch 11 & 12), Human Health and Disease (Ch 8), Ecosystem (Ch 14).
  • Lower priority (boards mostly): Ch 9 (Food Production) and Ch 16 (Environmental Issues) — know these but do not spend excessive time on them.

How to Practise Biology MCQs Effectively

After reading each NCERT Biology chapter:

  • Attempt 10 to 15 MCQs from that chapter immediately
  • Read the explanation for every wrong answer
  • Revise only the specific paragraph or concept you got wrong — not the full chapter
  • Come back to the same chapter after 3 days and attempt MCQs again
  • Once standard MCQs feel comfortable, practise Assertion-Reasoning MCQs from the same chapter.

At 30 minutes per day, you can cover all 16 Biology chapters in 6 to 7 weeks using this method.

Three MCQ-Heavy Areas in Class 12 Maths

  1. Calculus (Ch 5, 6, 7, 8): Application of Derivatives and Integrals carry the highest weightage. MCQs from these chapters appear in every board paper and in JEE Main 2027. Every hour spent here counts double.
  1. Probability (Ch 13): Conditional probability, Bayes theorem, and probability distributions appear as MCQs every year. These are conceptual — once the logic is clear, these become some of the easiest MCQs to answer correctly.
  1. Determinants and Matrices (Ch 3 & 4): Short MCQs solvable in 60 seconds with shortcut methods. High marks for low time investment — great chapters to build MCQ speed.

For JEE Main 2027 Students

JEE Main Maths has 20 MCQ questions plus 5 numerical questions. Practising all 13 Class 12 Maths chapters chapter-wise on the portal directly covers your JEE Maths syllabus. The portal also covers Class 11 Maths chapters — both years in one place.

Class 12 English MCQ — Do Not Lose Easy Marks Here — CBSE 2026-27

Why Science Students Skip English MCQs (And Why That is a Mistake)

Most Class 12 Science students think English is easy and skip MCQ practice for it. Then they sit in the exam and lose 6 to 8 marks in the reading comprehension and literature MCQ sections — marks that were very much within reach.

English has 80 marks in theory. MCQ elements appear in the Reading section and in the Literature section (Flamingo and Vistas). Fifteen minutes of daily practice is enough to protect these marks.

How to Practise English MCQs Without Spending Too Much Time

  • For comprehension MCQs: Read the passage quickly for the overall idea, then go back and find the answer in the text. Do not guess from memory.
  • For literature MCQs: Focus on the main theme, key events, and the character’s feelings in each chapter. MCQs test specific quotes and the author’s message.
  • For poetry MCQs: Focus on tone, imagery, and what the poet is saying. Literary device identification — metaphor, simile, personification — also appears.
  • 15 minutes of chapter-wise English MCQ practice daily is enough to score well in this section.

The NCERT Plus Method — How to Use MCQ Practice Alongside Your Textbook

Reading NCERT and practising MCQs are not two separate activities. The best students do them together. Here is a six-step daily method that works for all five subjects:

Step 1 — Read the chapter first. Understand the concept. Do not just scan for definitions or headings.

Step 2 — Attempt 10 to 15 MCQs immediately after reading. Your memory of the chapter is freshest right now. Test it.

Step 3 — Read the explanation for every wrong answer. This tells you why the wrong options were wrong — which stops you from making the same mistake again.

Step 4 — Revise only the specific topic you got wrong. Do not re-read the full chapter. Targeted revision saves 60% of your time.

Step 5 — Come back after 3 days. Attempt the same chapter’s MCQs again. If you get them right this time, you have retained the concept. If not, one more quick read of that section will fix it.

Step 6 — Add Assertion-Reasoning MCQs. Once standard MCQs from a chapter feel easy, move to A-R type questions from the same chapter. These are harder and will show whether your understanding is deep enough.

Time needed: 25 to 35 minutes per chapter per session. At 2 chapters per day across all subjects, you can cover the full Class 12 Science syllabus in 7 to 8 weeks — leaving 5 to 6 months for revision before February 2027 boards.

Frequently Asked Questions — Class 12 Science MCQ 2026-27

The CBSE Class 12 board paper for 2026-27 follows the 50-20-30 rule. This means 50% of the paper has competency-based questions — case-based MCQs, source-based MCQs, and assertion-reasoning MCQs. Another 20% consists of standard one-mark MCQs. Only 30% is written short and long answers. So nearly 70% of the paper has MCQ elements in some form. The exact number varies slightly by subject, but the 70% figure holds across Physics, Chemistry, Biology, Maths, and English.

The 50-20-30 rule refers to how CBSE distributes question types in the Class 12 board paper. 50% of marks come from competency-based questions — case-based MCQs, source-based MCQs, and assertion-reasoning questions. 20% comes from standard objective MCQs — simple one-mark questions. The remaining 30% is written answers. This pattern is in line with the National Education Policy 2020 and is designed to test application of knowledge, not just memorisation.

An assertion-reasoning MCQ gives you two statements — Assertion (A) and Reason (R). You decide: is A true? Is R true? And if both are true, does R correctly explain A? There are four possible options to choose from based on these combinations. This format was specifically introduced in Biology for the CBSE 2026-27 session. These questions cannot be answered by memorising text — you need clear conceptual understanding. Practising A-R MCQs chapter-wise before your board exam is the most effective preparation.

In the CBSE Class 12 Physics paper for 2026-27, Unit VI — Optics (Ray Optics and Wave Optics) carries 18 marks. Units III and IV together — covering Magnetic Effects, EM Induction, and Alternating Current — carry 17 marks each. Units I and II — covering Electrostatics and Current Electricity — carry 16 marks together. These five units account for more than 70% of the Physics theory paper. Focus your chapter-wise MCQ practice on these units first.

Yes, very much so. NEET UG 2027 is 100% MCQ-based, and Biology carries 360 marks out of 720. Class 12 Biology covers roughly half the NEET Biology syllabus. Chapters like Genetics (Ch 5 and 6), Human Reproduction (Ch 3), Biotechnology (Ch 11 and 12), and Human Health and Disease (Ch 8) appear in both CBSE boards and NEET. Practising chapter-wise Biology MCQs for boards simultaneously prepares you for NEET UG 2027 — no separate revision needed for these chapters.

No. CBSE Class 12 board exams do not have any negative marking. A wrong MCQ answer gets zero marks — it does not reduce your score. This is different from JEE Main 2027, which has a –1 penalty for wrong MCQ answers, and CUET UG 2027, which also has –1 marking. For your Class 12 boards, the best strategy is to attempt every MCQ — even if you are not fully sure. Educated guessing with option elimination can recover 1 to 2 marks per section.

Yes. The quiz portal at Aspirations Institute Test Portal is fully browser-based. You do not need to download any app on your Android or iOS phone. Open the portal in your phone’s browser, pick your subject and chapter, and start the test. The free 10-question sample works without any login or payment. The portal is designed to be fast, clean, and distraction-free — no ads, no pop-ups, no video interruptions while you are attempting a test.

If you practise 25 to 30 minutes per day and cover 2 chapters per session, you can complete all five Class 12 Science subjects — roughly 60 to 65 chapters — in 7 to 8 weeks. Starting in June 2026 gives you 8 to 9 months before the February 2027 boards, which allows for 2 to 3 full revision cycles. The key is to go chapter by chapter, not subject by subject. One chapter fully done is more useful than five chapters half-read.
