You can read it online with out any issue, you will get good enough knowledge through Telugu Academy Books. Best Thing is to Read or Download PDF of NCERT Books https://www.learncbse.in/ncert-books/ (or) buy selective books which can give you best results from NCERT Books.

Hello aspirant, 

NCERT books are issued by the Central Government whereas Teluguv Akadami books are issued by the state government. Also, teluguv akadami books have more information than Ncert books, if you want to prepare for any competitive exam. But for NEET Ncert biology book is better. Syllabus is same in both the books. 

Hope it helped!

Good Luck.
