What is more important topics to get good marks in eamcet

Hello,
First of all, blindly learn all concept, definitions & Formulae of 11th and 12th class syllabus. Byhard & practice them without seeing.

For Maths, learn some shortcut formulae that were derived in the textual examples.

For Chemistry, mostly theory part exists. So it's not a problem to remember it.

For Physics, practice formulae of main topic chapters which should be your last priority.

Thank you
