February 17 is right around the corner. Most Class 12 students are sitting with mountains of textbooks, wondering where to begin.
Here is what toppers know: Board exams do not reward those who read the most. They reward those who revise the smartest.
We have trained thousands of students at Aakash, and the trend has become evident. Those scoring 90+ possess the most strategic notes. If you are still thinking you will “cover everything,” stop. Let’s talk about what actually works, and what your final week before the exam should look like.
Class 12 Physics: Make Your Notes Formula-Friendly
Physics is not a reading subject. It is a doing subject. Your notes should reflect that. Instead of writing long explanations about concepts, focus on this structure:
- One formula per line, with the condition it applies to written next to it
- One solved example showing the formula in action, especially for Current Electricity, Optics, and Magnetism
- A mistakes column where you note down sign convention errors or unit mismatches you have made before
Here is the thing. Students lose their marks in Physics not because they do not know the formula, but because they use it in the wrong way. Your notes should prevent that.
For theory-heavy chapters like Semiconductor Devices or Communication Systems, stop writing paragraphs. Draw comparison boxes instead.
- n-type vs p-type.
- LED vs photodiode.
- AM vs FM.
Tables stick in memory better than sentences. Access our NCERT Solutions for Class 12 Physics if you need to understand any topic.
Chemistry: Split Your Notes Into Three Clear Parts
Chemistry Class 12 is not one subject. It is Physical + Organic + Inorganic. Treat them separately in your notes.
Physical Chemistry
Create a formula page per chapter. Electrochemistry, Solutions, Kinetics, these are all formula-application topics.
- Write the formula
- Write the units
- Write one standard question
That is it. If you are referring to Chemistry Class 12 NCERT solutions, extract only the formulas and sample problems. Leave the explanations behind.
Organic Chemistry
For organic chemistry, you need reaction flow maps. On a blank sheet, write the starting compound in the middle and draw an arrow to all the products that it can produce with the reagent written above the arrow. Each time you revise, you can see the entire picture in a single view. Not across 10 pages.
Inorganic Chemistry
D-block elements, Coordination Compounds, these chapters feel random, but are not. There are clear trends.
Make trend tables:
- Oxidation states across a period
- Magnetic behaviour patterns
- Colour changes with ligands
- Stability order of complexes
Your brain remembers patterns better than isolated facts. Use that.
NCERT Biology Class 12: Think Visual, Think Keywords
Biology has a reputation for being “easy if you read NCERT.” True, but only if you read it right.
In process-based chapters, such as DNA Replication or Protein Synthesis, your NCERT Biology Class 12 notes should be a numbered step-by-step list. Do not write “the enzyme helicase unwinds the DNA strand.” Write “Step 1: Helicase unwinds DNA.” Clear. Direct. Easy to recall.
Diagrams are non-negotiable in the NCERT Biology Class 12. These appear almost every year:
- Structure of a flower
- Human heart
- Nephron
- Antibody
But here is an important tip: do not just copy diagrams. Be able to draw them from memory and then check. Keep repeating until you can do it with your closed eyes. That is when it sticks.
Make lists of keywords in chapters such as Genetics, Evolution, or Ecology. CBSE examiners look for certain words when scanning answers. If those terms are missing, marks vanish. So, your NCERT Biology Class 12 revision notes should highlight 4-5 must-use keywords per concept.
Mathematics Class 12: One Sheet Per Chapter
Mathematics does not need detailed notes. It needs one thing: a formula and a property sheet you can revise in 10 minutes.
Your Mathematics Class 12 notes should fit on one A4 page per chapter. Write every formula, every property, every standard result. Nothing else. If you want to add one solved previous year question as a reference, fine. But do not turn it into a solution book.
These chapters are pattern-based:
- Calculus (heavily weighted in class 12 exams, about 30-35%)
- Matrices
- Vectors
- Probability
Once you know the formula, it is just about practising question types. So, your notes are not for learning. They are for quick recall before the exam.
One more thing. Write formulas with their conditions. “Integration by parts: use when product of two functions” is better than just writing the formula alone. Context helps memory.
English: Templates, Not Essays
English notes are the easiest to make and the most ignored. Do not make that mistake. For the writing section, create format templates.
- One sample formal letter.
- One sample article.
- One sample report.
For literature, do not write chapter summaries. Write character trait maps and theme pointers. If a question asks, “How is the theme of survival portrayed?” you should instantly know which chapter or poem to refer to and what line to quote. Your notes should make that instant.

Final Words
Success in CBSE Class 12 boards does not come from studying the most. It comes from studying the smartest. Follow this one week before each subject’s exam:
- Day 1–3: Go through your notes fully, add anything missing from PYQs
- Day 4–5: Solve 2 sample papers, time yourself
- Day 6: Revise notes again, focus on weak areas only
- Day 7: Light revision, no new material
If you are still adding new points in the final week, you are doing it wrong.
That concludes it. With the right strategy and consistent effort, you’re well-equipped to make your preparation count. You have got this! Now go make those notes count.
FAQs
Q1. Should I make separate notes for the NCERT and other books?
No. Stick to one set of notes per subject. Multiple notebooks create confusion, not clarity.
Q2. How detailed should subject-wise notes be?
Compact enough to revise in 2 hours per subject. Use bullets, tables, and diagrams, not paragraphs.
Q3. Is it too late to start making notes now?
Not at all. Give attention to high-weightage subjects. For NCERT Biology Class 12, prioritise Reproduction and Genetics. Quality beats coverage.
