Hello aspirant,

The syllabus of the entrance will cover mostly syllabus of BA(psychology) so you should start preparing with the basics.

Topics such as following 

• Individual psychology
• Child Psychology
• Clinical psychology
• Counseling psychology
• Social psychology
• Industrial psychology

If you have no basic idea then buy R.Gupta's book for preparation.
