Hi KIRAN,

Yes they are enough to get good marks especially the examples in mathematics text books.But for getting good rank you need to practise previous year question papers and need to work on basic formulae.

For EAMCET you may concentrate more on memorising things rather than solving.So my advise is to follow the text book and some reference books such as EAMCET physics and EAMCET mathematics by Deepthi publications.
