Hello dear ,

NCERT books for Class 11th and class 12th along with past year papers are good enough for EAMCET preparation. spend 2- 3 hours every day, for NCERT books and prepare for boards right from the start.  . Study more in textbooks because it contains more information  , you can give more time for same topics while studying for your board exams and study from the perspective of your competitive exam.

Good luck !
