Hello Nishad Sultana.

As you have gone through the previous eamcet papers you could have found that most of the questions of Eamcet exam are directly or indirectly related to the ncert text book.

If you go through the concept definition formulae of ncert text books understand them and solve problems related to them, then you can attempt the Eamcet exam with ease.

Especially coming to chemistry e most of the concepts asked in the EAMCET exam are almost directly related to the NCERT textbook and some of the questions of inorganic chemistry are directly asked in the EAMCET exam.

I am in mathematics if you go through all the example problems provided before the exercises to solve then questions will be asked from same methods and concepts.

If you are very good in NCERT textbooks and have practiced few previous years papers then you can attempt EAMCET exam with is and score decent rank in EAMCET exam which will automatically fetch a good rank and a good branch in a good college.

Good luck
