### CBSE Class 12 Mathematics Tips & Tricks

1. Students should start by preparing for long answer-type questions to boost their confidence for the rest of the journey. Try CBSE Question Banks Class 12 Maths for these questions.

2. The most important and easy-to-score topic is Calculus (44% weightage). Try to put more emphasis on unit of sum, maxima, and minima application problems, and application of integrals. Don’t forget to practice plotting graphs & labelling them.

3. Differential Equations may be appeared in application-based question format.

4. Vectors and 3D Geometry are equally important with 17% weightage and wouldn’t take much time.

5. Probability, Relations & Functions and Algebra have weightage 10%, 10% & 13% respectively, make plan accordingly.

6. Linear programming is although of 6% weightage, but it’s quite easy to master and just a little practice can add 6 marks directly to your preparations.

7. Matrices and Determinants, Matrix Method, Inverse of Square Matrix, and properties of determinants are important but are advised to be done at the latter stage. Concepts of Line and Plane in 3D is quite tiring at some points so you should finish this at early stages. Also, Bayes Theorem in Probability is much likely to come.

### Physical Chemistry

1. The biggest advice is to revise topics from NCERT to its fullest.

### Organic Chemistry

1. Systematic revision is required to score maximum. The types of questions asked are:

Reasoning based conceptual questions

Word Problems/ Conversions

Name Reactions

Reaction Mechanism

2. Don’t forget to revise chapters like Polymers and Bio-molecular as they are easy to score. These chapters carry 10 marks and therefore need proper attention.

### Inorganic Chemistry

1. Questions in this section are:

Reasoning-based

Structure-based

Complete the reaction

2. p-block elements: Students should revise all the reactions daily.

3. d and f-block elements: Reasoning-based questions; revise preparation structure and properties of compounds such as KMnO4and K2Cr2O

4. Coordination Compound: It’s a highly scoring chapter.

5. Metallurgy: Revision is the key for this chapter.

7. Electrostatics and Optics are very lengthy so you should prepare it in early stage.

10. These chapters that would take much time -
Magnetic properties of materials
Polarization
Optical Instrument
Electromagnetic Wave and Communication System
Semi-conductor
Diffraction

11. While solving numerical-type problems, make sure to use right values and the calculations should be correct.
