Dear friend ,
For Chemistry:

You should thoroughly read the textbook as 90% of the questions asked will be from the textbook.After you are thorough with the textbook, buy the TELEGU AKADEMI EAMCET materials and solve questions from that book.And don't forget to solve the example problems given in the textbook. That was all for Chemistry.

For Physics:

You need to learn all the concepts from the textbook and you should know the approach of solving problems. Physics is not that tough you just need some more effort to solve problems and some more practice too. Be well versed with all the formulas and practice as many problems as you can. For problems you can refer DEEPTI Physics and Telugu Akademi Eamcet Materials.
Work hard...
Good luck!!!!
