INTRODUCTION

Welcome to Part 25 of our continuing WBCHSE Class XII Semester III Model Question Bank series.

Reaching Part 25 is itself a reminder of one important principle:

Preparation becomes powerful when practice becomes consistent.

Students often spend a great deal of time collecting study materials but much less time analysing whether those materials are actually improving their ability to answer questions.

That is why this part is designed differently.

Here we will combine:

conceptual questions,

numerical problems,

case studies,

data interpretation,

assertion–reason,

HOTS,

answer-writing,

timed practice,

mistake analysis,

self-evaluation.

The objective is not simply to increase the number of questions solved.

The objective is to improve:

ACCURACY + UNDERSTANDING + SPEED + CONFIDENCE

Remember the preparation cycle:

Understand → Recall → Practise → Test → Analyse → Correct → Retest

Yes. A nucleotide substitution may be silent if the altered codon still specifies the same amino acid.

Question 37

No.

Mutations may be harmful, neutral or beneficial depending on their nature and biological/environmental context.

Question 40

The code is degenerate because several different codons can specify the same amino acid.

Question 44

The statement incorrectly implies that organisms deliberately create mutations because they need them. Mutations arise through biological processes; natural selection can favour variants that provide an advantage in a particular environment.

SECTION A — UNSEEN PASSAGE

Read carefully:

Effective preparation involves both study and reflection. Students sometimes complete many exercises without examining why their answers are wrong. Such practice can create the impression of progress without addressing weaknesses. A more useful approach is to review mistakes, identify the underlying cause and then attempt a similar question again. This process turns practice into learning.

Questions

What is the central idea?

Why may solving many exercises alone be insufficient?

What should a student do after making a mistake?

Find a word meaning “weak points”.

Give a suitable title.

PHYSICS

Question 75

Explain why the potential difference across an isolated capacitor can change when its capacitance changes.

CHEMISTRY

Question 76

Explain why a first-order reaction has a constant half-life at a fixed temperature.

BIOLOGICAL SCIENCE

Question 77

Explain how mutation can contribute to genetic variation.

MATHEMATICS

Question 78

Evaluate:

[ \int(4x^3-6x+2),dx ]

ENGLISH

Question 79

Write 120–150 words on:

BENGALI

প্রশ্ন ৮০

প্রায় ১৫০ শব্দে লেখো:

“নিয়মিত অনুশীলন কীভাবে আত্মবিশ্বাস বৃদ্ধি করে?”

GRAND MOCK ANSWERS

Physics

For an isolated capacitor, charge remains constant. Since:

[ V=\frac QC ]

a change in capacitance causes the potential difference to change.

Chemistry

For a first-order reaction:

[ t_{1/2}=\frac{0.693}{k} ]

At a fixed temperature, (k) remains constant, so the half-life remains constant.

Biology

Mutation can introduce changes in DNA sequence and therefore contribute to genetic variation within populations.

Mathematics

[ \int(4x^3-6x+2)dx ]

[ =x^4-3x^2+2x+C ]

PART VIII — EXAMINATION TIME MANAGEMENT

A good answer is not enough if the student cannot manage time.

Use the following strategy.

FIRST STAGE

Read the paper carefully.

Identify:

easy questions,

moderate questions,

difficult questions.

SECOND STAGE

Answer questions you know confidently.

This helps secure marks and reduces unnecessary pressure.

THIRD STAGE

Return to moderate questions.

Use your knowledge systematically.

FOURTH STAGE

Attempt difficult questions.

Do not spend an excessive amount of time on one question.

FINAL STAGE

Reserve time for checking.

Check:

question numbers,

calculations,

units,

diagrams,

signs,

incomplete answers.

PART IX — THE “THREE CHECKS” METHOD

Before finalising a numerical:

CHECK 1 — FORMULA

Did I use the correct formula?

CHECK 2 — CALCULATION

Did I calculate correctly?

CHECK 3 — UNIT

Is the final unit correct?

This simple habit can prevent many avoidable mistakes.

PART X — THE “THREE CHECKS” FOR THEORY

Before submitting a theory answer:

CHECK 1

Did I answer the exact question?

CHECK 2

Did I explain rather than merely state?

CHECK 3

Did I include important scientific/subject-specific terms?

PART XI — PERSONAL ERROR BOOK

Create one notebook titled:

MY MISTAKE BOOK

Divide it into six sections:

Physics

Chemistry

Biological Science

Mathematics

English

Bengali

For every important mistake, record:

Question

My answer

Correct answer

Why I was wrong

How I will avoid the mistake

This notebook can become one of the most valuable revision tools before examinations.

PART XII — 48-HOUR RETEST SYSTEM

When you make an important mistake:

Day 1

Correct it.

Day 2

Solve a similar question.

Day 3

Solve the original question again without looking at the answer.

If you can now solve it independently, the concept has become stronger.

PART XIII — STUDENT SELF-EVALUATION

At the end of every practice session, complete:

Question

Answer

Did I understand today's concepts?

Yes / No

Did I practise without copying?

Yes / No

Did I analyse mistakes?

Yes / No

Did I revise previous mistakes?

Yes / No

Did I manage time properly?

Yes / No

What needs improvement tomorrow?

______

This takes only a few minutes.

But it turns preparation into a measurable process.

PART XIV — PARENT SUPPORT GUIDE

Parents can support students without creating unnecessary examination pressure.

Try asking:

“Which topic did you understand best today?”

Then:

“Which topic needs another revision?”

And finally:

“What is your plan for tomorrow?”

This creates responsibility without turning every conversation into a marks discussion.

PART XV — 7-DAY MASTER REVISION

DAY 1

Physics:

Concepts + numericals.

DAY 2

Chemistry:

Electrochemistry + kinetics + coordination.

DAY 3

Biology:

Molecular biology + mutation + evolution + diagrams.

Reading + grammar + writing + literature.

DAY 6

Bengali:

গদ্য + পদ্য + ব্যাকরণ + রচনা + বিশ্লেষণধর্মী উত্তর।

DAY 7

Full mock examination.

Then analyse every mistake.

PART XVI — FINAL REVISION FORMULA

For Science:

Concept → Formula → Application → Explanation

For Mathematics:

Method → Calculation → Verification

For English:

Read → Understand → Organise → Write → Edit

For Bengali:

পড়ো → বোঝো → বিশ্লেষণ করো → নিজের ভাষায় লেখো → সংশোধন করো

For the entire examination:

Practice → Test → Mistake → Correction → Retest

FINAL MESSAGE TO STUDENTS

Dear students,

Part 25 is not about proving that you know everything.

It is about discovering what still needs improvement.

If you make mistakes in this practice set, do not become discouraged.

Instead, ask:

Why did I make the mistake?

Was it:

lack of knowledge?

confusion between two concepts?

calculation error?

careless reading?

poor time management?

incomplete answer?

Once you know the reason, correction becomes much easier.

Remember:

A test is not only a measurement of preparation. It is also a tool for improving preparation.

So keep your practice honest.

Do not look at the answer before attempting the question.

Do not copy a solution and assume the concept is understood.

Try first.

Make mistakes if necessary.

Then correct them.

Then try again.

That is how confidence is built—not from avoiding difficult questions, but from gradually becoming capable of solving them.

Your preparation formula:

Learn deeply.

Practise honestly.

Test regularly.

Analyse mistakes.

Correct patiently.

Retest repeatedly.

And most importantly:

Never let one difficult chapter convince you that you cannot learn it.

A difficult chapter is simply a chapter that needs more time.
