Hello Student,

Some of the good books for preparation for COMEDK are as follows-

• NCERT Textbooks
• JEE Main and Advanced Preparation Books
• HC Verma for Physics
• JD Lee Concise Inorganic Chemistry
• RD Sharma Objective Mathematics

From my point of view NCERT are the best books for self study as it helps in basic knowledge. Solve previous years question paper to get an idea of the type of questioned asked.

Hope it helped you 

Thank you
