I am not prepared B.voc entrance

Hello,

for bachelor's UG admission:- Syllabus is given by the organizing body along with prescribed books.  Go to the official webpage and get syllabus. there you will get book list too.

you have not mentioned which exam you are appearing which is making difficult to know book details. Please do mention it in the comment section to provide you more precise details.

if exam syllabus is aptitude, verbal- non-verbal reasoning, logical reasoning then prefer RS agarwal. It has good question bank. You can do self-study as the examples in each chapter is good enough to teach you tricks. You will learn it very easily.

For GK, you can check current affairs.

Hope it helps!
