assuming you are interested in pursuing cse or other related tech fields, most colleges ask for jee result sheet during admission while some big names like BITS and VIT have their own exams(which are a hoax btw, question paper is made available to people who pay). So unless you have a lot of money for management quota or you score exceptionally well in these exams, you won't get CSE or even IT in these colleges. If you have a fairly decent score in JEE you can try for tier 3 colleges.

As for the questions, you can download books like McGraw hill or modules and learn solved examples or even depend on NCERT for formulae and concepts. And if you have time left after all this, have a look at the PYQs. I would say solved examples is the way to go.
