I don't know anything to write in ap eamcet.Any tips to get below 10,000 rank in eamcet ?

Hello aspirant!

Actually you don't have to study separately because as you have already studied for board exams for 11th and 12th that will be enough. Even you don't practice you can qualify in the exam with knowing concepts in 11th and 12th classes. As for getting rank below 10k you can refer previous question papers and do practice thoroughly and the related concepts that came in previous question papers practice that. As for chemistry NCERT  text book will be enough you don't have to refer any other references. So practice thoroughly that makes you perfect and strong in every concept and subject.

GOOD LUCK!
