dear student

For any examination a prime method of preparation should be to go through the past year papers and mocks.

Other than this, the syllabus is easy to moderate level quant, verbal, and logical reasoning. The general awareness questions are more specific and on the difficult side.

Focus on current affairs, economics, politics, amongst other things. Manorama Yearbook is an excellent book for preparing for Tissnet GA section. The examination is of 100 marks and depending on your course and cut off you can be required to score anywhere from 60 to 85 marks

For quant, Logical reasoning and Data interpretation you can refer R s agarwal, Arun sharma, Rd Sharma

hoept this helps

All the best!!!
