# How to score 100/100 in Maths (PCB) in Class 11th and 12th CBSE Board

Mathematics is a nightmare for many students and most of them struggle to get through it. But on the brighter side, it is also the subject where scoring a centum is possible. It is an unavoidable subject for JEE and Engineering aspirants. That said, it a subject that is loved and revered. Mathematics also helps the student in developing logical and rational thinking. The class 12 board score makes a huge influence on further studies and a 100/100 in maths will be very helpful in gaining a very good grade.

Now, coming to CBSE maths, it is one of the toughest paper one encounters with and scoring 100 in CBSE maths requires hard work, lots of practice and dedication. There are no shortcuts except working hard to achieve the marks. Class 11 and Class 12 is a crucial stage that decides the course of student’s further studies. It is very important for engineering aspirants to master and score well in Physics, Chemistry and Mathematics.

## Let us first have a look at the CBSE Maths exam pattern for Class 12

CBSE has made considerable changes in the exam pattern for the March 2020 board examination. Important points associated with the new change is as follows:

• Internal assessment to be included for maths exam

• The final maths exam will be for 80 marks and internal exam will be for 20 marks (earlier the exam had a single paper for maths exam which carried 100 full marks)

• The internal assessment will act as a criterion for the final exam. Schools will conduct internal exams and the students who pass will only be allowed to write the final exam

Note

Out of 20 marks for the internal assessment, 10 marks will be taken from the results of the school exams and the remaining 10 marks will be taken from the internal evaluation done.

The proposed format of internal assessment in CBSE Class 12 Maths subject is as follows:

Sl No

Unit Name

Marks

1

Relations and Functions

8

2

Algebra

10

3

Calculus

35

4

Vectors and Three - Dimensional Geometry

14

5

Linear Programming

05

6

Probability

08

Total

80

Internal Assessment

20

### Some other significant changes

CBSE will be introducing 25% MCQs in all the subjects for the exam. So out of 80 marks, 60 marks will be dedicated for subjective type questions and the remaining for objective type questions. The number of internal choices was increased by 33% in 2019 examinations and the same will continue for this year. CBSE is thinking to conduct practical examinations at the external centres, though no official statement is made in this regard.

The percentage of objective-type questions is 25% and the number of descriptive questions is 12 (it has been significantly reduced) for the year 2020. Practical marks will range from 30 to 70.

### Weightage

The important topic that has about 44% weightage attached to it is Calculus.

Calculus has around 44% of weightage attached to it, Vectors and 3D geometry about 17%, Probability, Relations and Functions and Algebra have a weightage of 10%, 10% and 13% respectively whereas, Linear Programming is 6%. Students can prioritise the order of learning by marking calculus first, followed by vectors and 3D geometry and so on. This way they can save time. The chapter dedicated to Differential equations contains the application based difficult questions.

The other important topics are

• Integration

• Differentiation

• Matrices and determinants

• Relations and functions

• Probability

• Limits

### How do you practice/ during exam preparation

Understand your syllabus: The first step in preparation is to know what you must prepare for. The syllabus plays an important role in that. NCERT textbooks are recommended to prepare for the CBSE board exam. It is no exaggeration when people say that NCERT is the holy book for CBSE examinations! Know the weightage given to each topic in the syllabus and plan your learning according to it.

Theorems and Formulae: Maintain a separate register or handbook for theorems and formulas. It is better to make of note of every formula. Also, note down the graphs needed in case of calculus.

Say no to mug ups: It is easy to fall for mug up trap but in the long run it does not help much. So learn to solve the problems yourself, practice on how to apply the formulae and theorem for a problem, understand how it works, try to twist the problem and see if you can solve it.

Miscellaneous problems: How many of the time have you skipped those ‘Miscellaneous problems’, ‘do it yourself’ problems given at the end of each chapter? Never skip those if you want a centum in maths. Start solving all the solved and unsolved problems in NCERT textbooks.

Practice papers: Have a look at the past exam papers of CBSE Maths to get an idea of how the questions are asked in the exam. Don’t waste time on easy problems but focus more on difficult and twisted problems. Practice them keeping the time limit in mind.

Address your problems: Never postpone to solve the problems, address them with a calm mind. Postponing to solve twisted or big problems might cost you too much in the later period, so address them now!

Time management: Managing the time is the key factor in preparing for board exams. It is easy to lose the track of time in solving tough problems in maths and hence it is essential to practice the problems within the time limit. Take mock tests online to get that exam feel and practice more in that scenario.

Clear your doubts: Don’t shy away to ask questions and clear your doubts however silly it may sound. It is better to solve now than to feel sorry later.

### What to keep in mind during the exam

• Maintain a Clean Paper and margin

• Steps are important in solving as marks are given for each step

• Let the Figures and Graphs be clear and understandable. Label them appropriately

• Always finish familiar questions first

• Avoid Overwriting and Scribbling

• Spare some time to revise everything you wrote
