CBSE Practical Exams 2026: Board Announces Full Schedule, Instructions and Assessment Rules

With just two months left for the board exams, many students wonder if starting now can still lead to a 90–95 score in Chemistry. The answer given in this session is clear: you can score a perfect 100/100 in the next 45 days if you follow the right strategy with discipline.

 Ms. Tapur Umar, begins by breaking down the subject and explaining how students should utilise the remaining time with smart planning.

Understanding the Structure of Class 12 Chemistry

Chemistry is divided into two books, with a total of 10 chapters:

  • Physical Chemistry – 3 chapters

  • Inorganic Chemistry – 2 chapters

  • Organic Chemistry – 5 chapters

Before starting preparation, students must analyse the marks weightage of each chapter. The biggest mistake is giving equal time to all chapters without considering which ones carry more marks.
A 5-mark chapter should not get the same number of hours as a 9-mark chapter.

Instead, students should identify:

  • Chapters with high weightage

  • Chapters that can be completed quickly

  • Chapters from which predictable questions are asked every year

For example, Biomolecules, a 7-mark chapter, can be mastered in just 3 hours if studied smartly.

Why Strategy Matters More Than Hard Work

The educator emphasizes that studying everything “as it is” is not possible in the last 45 days. Students must focus on:

  • What types of questions are asked

  • Which topics repeat every year

  • Which reactions or numerical types are most important

Organic Chemistry, for instance, demands that students separate and revise all name reactions carefully. Physical Chemistry requires focus on key numerical topics like Gibbs energy and Electrochemistry.

Can Every Student Follow This Strategy Alone?

Students are asked to reflect honestly:
“Can you follow everything consistently on your own for 45 days?”

Most students answer No or Maybe, and that’s the reality. The educator explains that guidance in the last 45 days acts as a catalyst, helping students avoid mistakes and save time. This is why a 45-day crash course, Nirbhay Batch, is offered for those who need structured help.

The batch includes live classes, doubt sessions, and complete guidance, ensuring nothing outside the taught material appears in the exam.

Step 1: Finish the Entire Syllabus — But in a Smart Way

Completing the syllabus does not just mean reading all chapters. It means:

  • Covering every chapter quickly through

    • YouTube one-shot videos

    • Recorded batch sessions

    • Summary notes (only if previously prepared well)

  • Immediately solving questions after each topic

Students should not attempt long coaching-style 10-hour classes now. Instead, they should use crisp, 2–3 hour one-shot lectures to complete chapters efficiently.

Step 2: Solve the Right Questions

When it comes to question practice, the educator stresses:

You do not need hundreds of reference books.

The only essential sources are:

  • NCERT textbook questions

  • CBSE Sample Papers

  • Last 5–10 years of Previous Year Questions (PYQs)

Chemistry repeats patterns heavily. Even when questions are twisted, they revolve around the same concepts.

Sticking to these three sources for the next 45 days is more than enough to score full marks.

Step 3: Frequent Revision

Students often skip revision, believing that finishing the syllabus is enough. But frequent revision is the real game-changer.

Revision should work like this:

  • After finishing Chapter 1, move to Chapter 2

  • After reading Chapter 2, quickly review Chapter 1

  • After reaching Chapter 9, check whether you remember Chapter 3 concepts

This helps identify what concepts are disappearing from memory so they can be strengthened in time.

Short notes, self-tests, and quick numerical checks help track actual understanding.

Step 4: Maintain Consistency for 43–45 Days

The educator stresses that 97–98 out of 100 students fail because they lack consistency, not because they lack ability.

Even the best strategy fails without consistency.

If students follow the plan daily for 45 days, without taking long breaks or losing focus, they can easily score 100/100.

Are You Able to Do This Alone?

Students who can:

  • study every topic,

  • solve NCERT + PYQ + sample papers,

  • revise frequently, and

  • stay consistent for 45 days

don’t need any external help.

But those who answered No or Maybe may require structured guidance like the Nirbhay or Nirbhay Pro batches, depending on whether they are preparing only for boards or for CUET as well.

The educator emphasizes that joining is entirely the student’s choice, but honesty with oneself is important.

Why Chemistry Is a Scoring Subject

Chemistry greatly impacts the overall percentage.
If students score well here, it can compensate for a slightly lower score in another subject. That’s why scoring 95–100 in Chemistry is not just possible—it is extremely achievable with the right approach.

Final Words

The educator guarantees that following this strategy with consistency will enable students to score 100 out of 100 in Chemistry.

  • Stay focused

  • Avoid distractions

  • Use the remaining time wisely

  • Revise frequently

  • Stick to NCERT, sample papers, and previous year questions

With discipline and smart work, scoring full marks is completely attainable.

How to Score 100/100 in Chemistry in the Last 45 Days: A Complete Strategy FAQs

Which resources should I use during the 45 day plan?
