Sir best book and martial of bhu entrance exazamination
Hello Karan,
There is no any particular books to prepare the exam so it is advisable to revise what you have studied in your class 12th to take admission for UnderGraduate programmes & Prefer the Graduation syllabus if you are preparing for Post Graduate programmes and apart from that you can go for sample and previous year papers as these would be helping you to know the difficulty level along with the paper pattern as well.
You can download the sample papers with the given below link.

In case you are asking for any other programme then let me know.
Good Luck!
