Hello Dereik Antony. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

I would first like to direct your attention to the AEEE syllabus elaborated in this Shiksha article:

• https://www.shiksha.com/college/amrita-school-of-engineering-amrita-vishwa-vidyapeetham-university-coimbatore-ase-coimbatore/exams/aeee/syllabus

Having studied in CBSE myself, I felt that all these topics were covered in the NCET textbooks of class 11 and 12. But, this is my opinion, as I don't know which state board you are studying in and what topics are covered in that.

But, if you are in Tamilnadu, then I can definitely tell you that your TN State Board textbooks will not help you one bit. NCET textbooks are the way to go. 

Hope this helps you and all the best!
