I have a few friends who graduated from AKTU. Here are the books they recommend for Maths, basic Electrical Engineering, and Electronics.

• Maths 1 & 2 - H.K. Das
• Basic Electrical - Basic Electrical Engineering by Ashfaq Hussain and Fundamental of Electrical Engineering by Vincent Del Toro
• Basic Electronics - Microelectronics Circuits by Sedra Smith
• C Programming - Let Us C by Yashwant Kanetkar 

The two basic Electrical Engineering books will be useful in all 4 years of your study. These books are great for solving doubts.
