Hello,

Unfortunately, it is difficult to get everything in one book. To make the preparation better the students should read from different reference book for each of the subjects to become better in it. The subject wise book list is as follows:

1. Quantitative Aptitude by RS Agarwal for Mathematics or Numerical Ability

2. Objective General English by S.P. Bakshi, English- from Plinth to Paramount by Neetu Singh.

3. Manorama Yearbook for GK and Current Affairs, Daily newspaper reading/magazine reading.

4. Computer Knowledge by Dr. Alok Kumar

These are some of the good books to prepare in a better way for the exam. There are other books available in the market as well.
