How to get 90%+ in CBSE 12th Board in a Year-Board Exam Preparation Strategy

During my 12th, I didn’t prepare for CBSE Boards for the whole year. I did it in just 15 days and got 94, 94, 95, 94 board marks in Physics, Chemistry, Maths and English respectively.

But does it mean, you can just wait for the whole year and start preparing for your board exams just before 15 days ? – No

You can only prepare for CBSE Boards in 15 days only if you have good knowledge of the chapters beforehand. Although I think one year is more than enough to prepare for CBSE Board Exams, but if you do it, you have a better chance to score higher marks.

So, Let me ask you a Question : Are you doing coaching for JEE/PMT?

  • If Yes – Then, focus on your coaching studies. And if you are performing good in your coaching, you will easily be able get 90% by studying in last 15 days. Go through my blog How I got 90%+ in 15 days in CBSE 12th Board, where I have described how you can get good marks by preparing in last few days.
  • If No – Then, You have good amount of time to prepare for Boards if you start now. I will be describing in this blog how you should prepare.

Let us go subject wise.

English –

Firstly, get the NCERT text book of English i.e. Flamingo, Vistas and one of the Extended reading texts. And you should get Golden Guide for English as well. Take one chapter at a time, read it nicely, take the help of the Hindi translated text, if you want, for each para and if then also you do not understand, read the summary for that chapter from Golden guide once and then start over that chapter again. You should always make sure that you understand the chapter nicely as there are few chapters which has a deeper meaning than it looks from top and questions related to it comes in exams. After every chapter, go through the questions and answers present in Golden Guide as it will give you an idea of how to write the answers and what teachers are expecting from you. For the Language part. It contains –

  • Short Answer Questions :- Advertisement or notice, drafting poster, writing formal or informal invitation or replies.
  • Long Answer Questions:- Letters based on verbal or visual input. Letters may include Business or Official Letters, Letter to editor, Application for Job etc.
  • Long Answer Questions :- Article, debate, speech or report.


Now, as you have ample time, you should go through each one of them and look through their examples. You will get to see that each type eg: report, has a specific type of template to write and there are only small changes you need to make for different reports. So, you should jot down those templates and then choose which one to write in the exams. Let’s say you have chosen report, then practice some questions on report. But note this, after the initial rigorous practice, you should keep a time separate every weekend when you should practice at least one report. You will also get passages in exams. They will be long and you should practice reading fast and simultaneously understanding passages. You may be asked to write summary for the passage, so do practice it every weekend as it has a specific format and if you do not follow it, you will not get any marks.

Physics –

SectionNo. of QuestionsMarks/Question

For Physics, it is important to learn and understand by writing. Firstly, you should go through the chapters thoroughly and then the Question and answers at the end of the chapter. Do write each and every answer in a copy in a very described and step wise manner, so that, in the last few months, you can just look through that copy for answers. For each chapter, do practice the diagrams nicely, never forget the labels and the heading of the diagram. And you should always write a brief description of what is being shown in the diagram. You should note down every derivation or proof and procedures, and practice it over and over, as they will fetch you maximum marks. After every chapter, go through past few years question papers and see if there is some other questions available which were not present in the Q/A part, if so, then mark those questions and practice them as they are frequently asked. But note there will always be few questions of 1-2 marks which you will not find easily in question-answers part. For this you have to go through each and every line of the chapter nicely, do not take any part lightly. Moreover, the way you present your answers matters a lot. I and one of my friend wrote almost the same answer to a question, but as that question required steps, he wrote in paragraph format, but I wrote it in steps and I got better marks. So, the more you can present your answer better, the more you have a chance to get better marks. Whenever there is a proof or procedure, do write the reason of every step you do. Physics is easy, you just need to focus on the important things and there may be many people who will recommend you Exam Idea book for it, but believe me, if you devote same amount of time you put in completing Exam Idea in NCERT and past years question papers, you will get much better marks.

Chemistry –

SectionQuestion No.Marks/Question
A1 - 51
B6 - 102
C11 - 223
E24 - 265

For Chemistry, NCERT is like “Bible”. 90-95% of the questions in the Board exams will come from the Q/A part of NCERT book. You need to read each line carefully and every sub part of the chapter is very important. Do not skip anything. In Organic Chemistry, go through the structures, reactions carefully and the reasoning behind each step in the reactions. You should practice the structures and reactions by drawing it repeatedly. You should revise the portions of Organic which you have already done every week as it is tough to remember all the reactions. You can solve Physical Chemistry problem by understanding and practicing the concepts, but this doesn’t hold same for Organic and Inorganic Chemistry, you have to make sure that you have learnt all the things before the exams, don’t think that you can understand and solve it at that time. There are students who do answer Inorganic and Organic by understanding concepts, but its true only for few students.

Maths –

In Maths, you have 4 sections – A, B, C, D.

SectionQuestion No.Marks/Question
A1 - 41
B5 - 122
C13 - 234
D24 - 296

Section A – Contains questions which are very easy and you can directly solve it by looking.

Section B – Contains questions which are easy and based on standard formulas, but you need to write it and solve, its tough to solve it in mind. But if you keep your mind calm and have practiced well, you will easily solve it. Mostly the problems will be of “Solve” or “Evaluate” type.

Section C –  Contains questions which are of medium level. Mostly of “Proof” or good “Evaluation” problem. This will actually test your Math skills. You need to first understand the problem nicely, and make the framework of the solution in mind before you actually solve it.

Section D – Contains questions which have 2 or more sub parts. And the 2nd part is related to 1st part. So, if you can solve the 1st part, it gives you a hint to solve the 2nd part.

For every mark you should at least write 1/4th of the page. It is correct that in Maths the length of Answer doesn’t matter, but believe me, it does have a psychological effect and teachers tend to give more marks. So, for 1, 2, 4, 6 mark questions, You need to write 1/4th, 1/2th, 1 and 1.5 pages respectively.

Now, how to prepare Maths. As you know Maths is all about practice. You need to go through the chapters in the same order as given in the book, as most of the chapters are interconnected and you need to have the knowledge of the previous chapters to solve the next one. The most important thing is that you should take some time every 10 days to solve few randomly picked problems of the already completed chapters, so that you remember every concept nicely. Do practice the example questions nicely as it will cover most of the different type of questions. Focus on writing answers stepwise and do write reasons stating the reason why or how you come to some step from previous step.

Make sure that you complete your syllabus at least 3 months before Board Exams, so that you can practice lots of previous years and sample question papers and revise.

So, these are the basic strategies, you should follow in order to excel in CBSE Board 12th.
