Planning to give GATE exam? Searching for the important subjects for this exam preparation? Find advice from experts on this page.

As a Computer science student I want to know about the key subjects for getting admission in the celebrated institutes over the India. I have some required knowledge to prepare for the GATE but according to me that knowledge is deficient for achieving my dream.
Experts: do respond.

• As you are a computer science student I am going to provide the best books
for GATE Exam
preparation based on the
following important
considerations.
a. Strictly covers the GATE
syllabus
b. Easy to learn and
understand the concepts
c. Popularity and Standard
book
