Mathematics Preparation Tips for NDA Exam

The candidates must have a clear understanding of the syllabus & should note important and scoring topics based on the analysis of previous year papers.
The candidates should make a proper time table allotting more time to important & high weightage topics.
The candidates should solve online mock papers to get the real feel of examination & get habitual with time bounded practice. It will develop the ability to solve maximum questions in limited time. Also solve previous year questions chapter wise to get the understanding of level of questions that are asked.
The candidates should learn shortcut tricks that can come handy during the exam time. You can refer to You Tube videos for that.
The candidates should remember fast calculation techniques for finding squares & cubes.
Make a important formula & shortcuts notes for quick revision.
The candidates should focus on developing the accuracy while solving the problems in time bound manner. One wrong question can keep you out of the race.

Here are the details of important topics for NDA Mathematics section

Algebra - Questions that are asked from this section are usually easy. Most questions are formula & result oriented. So make sure you remember all the important results of complex numbers (cube root of unity, conjugate, etc), Binomial theorem, P&C.
Calculus - It has important chapters like Application of derivatives, differentiation, definite integral, Area under the curve etc. If you develop good understanding of graphs & how to use them, you can score good marks in this section
Coordinate Geometry - This is most scoring topics in NDA. This is another topic that can help you to acquire maximum marks.

Give more importance to chapters like Vectors, complex number and 3-D as compared to Probability or Indefinite integration. Most of the questions asked are result based. so make sure you maintain notes of all important formulas & results.
