which are are good coaching institute in bangalore???

there are threads with address and reviews of classes in Bangalore.

is it worth joining it??

depends on the way you look at it.

how much necessary is to join a coaching in preparation for CSE??

it gives you basic idea about how to prepare, what books to read, what strategy to keep up, etc. and teaches you the standard topics, and takes regular tests- so you keep reading and preparing. also, it helps if you are completely unfamiliar with the subject like the science grad taking a literature subject.
apart from that, they can't teach you anything that's not written in some book already, so coaching classes help but its not like you can't pass out with out going to coaching classes.

is its always good to join a coaching class?.

depends on the quality of the coaching class.
joing classes have their own advantaegs but you can still do it on your own, provided that you know which books to read and how to study- refer the psychology forum for the tips on it.

they even provide study material??

big coaching classes provide their own printed notes.
but they're not and can never be the substitute for the standard books.

or better to get books and guides and start preparing by myself??

yes that's the best way.
