Engineering Mathematics:

Every topic from this subject is very important.

This subject is a scoring one.

One should not leave any topic from this subject as all the questions asked from this subject are having the same level.

Engineering Mathematics by Grewal textbook covers all the topics. Solve all the examples of the book along with previous GATE papers.

General Aptitude:

Important topics covered in GATE:

Sentence completion and word analogies

Numerical computation and data interpretation

You need to be well versed with all important tipics which have more weightage.

Try to grasp the fundamentals and solve more than 50+ questions from each chapter and solve as many mock exams as you can to eliminate your weak areas.



Try Revising formulae and approach required in solving weak areas.



Top chapters for preparing are as :--

• Engineering mechanics
