The Chemistry Class 12 board exam is 70 marks of theory, and it rewards students who know exactly what to study, not just how hard to study. With a clear purpose, five days before the exam are sufficient to transition from scattered preparation to execution with confidence.
This is not about re-reading the entire NCERT from page one. It is about knowing which chapters carry the most marks, where students consistently lose easy marks, and how to use class 12 Chemistry notes and sample papers to become exam-ready fast. Here is the plan, curated by Aakash experts.
Understand the Class 12 Chemistry Paper First
The Chemistry class 12 question paper contains around 33 questions that have 5 sections (MCQs, short answers B & C, case-based, and long answers), amounting to 70 marks of theory. Before any revision, know exactly where marks are concentrated.
| Chapter | Marks | Weightage |
| Electrochemistry | 9 | 13% |
| Aldehydes, Ketones & Carboxylic Acids | 8 | 11% |
| Solutions | 7 | 10% |
| Chemical Kinetics | 7 | 10% |
| d- and f-Block Elements | 7 | 10% |
| Coordination Compounds | 7 | 10% |
| Biomolecules | 7 | 10% |
| Haloalkanes & Haloarenes | 6 | 9% |
| Alcohols, Phenols & Ethers | 6 | 9% |
| Amines | 6 | 9% |
| Total | 70 | 100% |

Day-by-Day Study Plan for Chemistry Class 12
This is how Aakash structures the final 5 days for students targeting 95+ from Chemistry Class 12 syllabus. Every day has a specific purpose. Do not mix them.
Day 1 : Physical Chemistry (23 marks)
Start with Electrochemistry, it is the single biggest chapter at 9 marks, and it is almost entirely numerical.
- Nernst equation, Kohlrausch’s Law, and cell EMF are not concepts you can “roughly remember.” You either know the formula or you drop marks.
Pair it with Solutions and Chemical Kinetics. Use your class 12 Chemistry notes to revise formulas quickly, not to re-read theory from scratch.
Day 2: Inorganic Chemistry (14 marks)
Two chapters, 14 marks, and almost zero numericals. That is good news. The bad news is that students underestimate Coordination Compounds and skip isomerism, and then lose 2-3 marks on it every single year. Do not make that mistake. Cover:
- Oxidation states
- Lanthanoid contraction in d- and f-Block
- IUPAC naming
- Isomerism in Coordination Compounds.
Day 3 : Organic Chemistry (33 marks)
Organic gets two days because it deserves two days. 33 marks. Nearly half the paper.
- On Day 3, tackle Haloalkanes and Alcohols, Phenols & Ethers. The SN1 vs SN2 distinction trips up a lot of students who don’t understand the mechanism, but do not only memorise the outcomes.
- On Day 4, move to Aldehydes, Ketones & Carboxylic Acids and Amines. Aldol condensation, Cannizzaro reaction, Hinsberg test. These named reactions are board exam staples.
Day 4: Biomolecules + Gap Filling
Biomolecules are 7 marks of almost pure theory. Focus on:
These are some of the most predictable marks in the paper. Do not skip them just to study “harder” chapters.
Use the rest of Day 5 to go back through Days 1-4 and fix any gaps using Chemistry class 12 NCERT solutions. Every board question traces back to NCERT. If something felt shaky earlier in the week, today is when you fix it.
Day 5:
Full Mock Test
Sit with a Chemistry Sample Paper Class 12 for 3 full hours.
- No breaks
- No peeking at notes mid-paper.
- Treat it exactly like the real exam.
After you finish, go section by section and note every question you got wrong or were unsure about. That error log is your Day 5 plan.
Students who solve at least two complete sample papers before boards score significantly higher on average compared to students who merely revise theory. That gap is real.
Targeted Revision Only
Do not study anything new today.
- Go through your error log from Day 5,
- Revise 1–2 sets of Chemistry previous year question paper class 12 for question pattern familiarity
- Do a final pass on electrochemistry formulas, naming reactions, and IUPAC rules.
That is it. You are ready.
Expert Study Tips for Exams: What Toppers Do Differently?
After training lakhs of students for Chemistry Class 12 boards, Aakash has noticed these habits that actually separate 95+ scorers from the rest:
- NCERT first, always. Every direct question traces back to NCERT. Solve every back exercise, no skipping.
- Draw mechanisms, don’t describe them. A clean SN2 mechanism = full marks. A paragraph about it = half marks.
- Long answers = 5 bullet points, not an essay. CBSE Section E awards marks for 5 distinct points. Write structured answers, not walls of text.
- MCQs are 16 free marks, don’t lose them. Shaky on Nernst equation or IUPAC naming? You’ll drop 4-5 marks in Section A alone.
- Named reactions = write, not read. If you can’t write it from memory, you haven’t learnt it.

Conclusion: What to Prioritise Right Now?
Look at the 5-day plan one more time. Find the days where your preparation is weakest and give those extra time.
Chemistry Class 12 does not reward last-minute reading. It rewards students who:
- Revise the correct chapters
- Study the correct paper format
- Walk into the exam knowing exactly what to expect
Good luck with your preparation! We’re rooting for you.
FAQs
Q1. How important are practical marks for reaching 95+ in Chemistry Class 12?
Practicals contribute 30 marks out of 100 in Chemistry Class 12. Scoring 25-28 in practicals is very achievable with consistent lab record maintenance and thorough preparation of Salt Analysis and Volumetric Analysis, which carry 8 marks each. A strong practical score takes significant pressure off the theory paper.
Q2. Can a student score full marks in Section A MCQs through the NCERT alone?
Most MCQs in the Chemistry class 12 question paper are NCERT-based, but some require the application of concepts. Solving the CBSE Chemistry Sample Paper Class 12 and at least 3 years of Chemistry previous year question paper class 12 is essential to encounter the variety of MCQ formats that appear.
Q3. What is the best way to revise Organic Chemistry in 2 days without getting overwhelmed?
Focus on named reactions and mechanisms, not every single transformation in each chapter. There are approximately 18-20 named reactions across the entire NCERT Class 12 Chemistry syllabus. Write each one from memory at least twice. Pair this with solving 1 set of previous year Organic questions to identify which reactions repeat most frequently.
