Hi aspirant,

First of all its not a complete question as you have not mentioned the subjects you have as it varies from college to college. Assuming you are talking about the first semester end exam I am recommending some books for common subjects:

• Engineering Mathematics- BS Grewal and Thomas (Pearson publications)
• BEE- DC Kulshreshta
• Engineering Chemistry - Jain and Jain
• Engineering Physics- Fundamentals of Physics by D. Halliday, R. Resnick, and J. Walker
• Python/ Java-- Eric Mathhes

Hope it helps!!
