Selection process that I have to undergo to pursue a graduate or post-graduate course

Is there a selection process that I have to undergo to pursue a graduate or post-graduate course?

Yes, there is a selection process that you have to go through to pursue the graduate courses (B.E. / B.Tech). The selection is based on merit i.e. the marks secured in the final exams of 10+2 and through entrance exams. Entrances to the IIT’s are through ‘JEE’ (Joint Entrance Exam) and for other institutions through their own separate entrance exams and other state level and national level exams. Apart from the IIT's, some other famous institutes also recognize JEE scores for selection. The national level exam AIEEE is also conducted for admissions in the NITs in India and many other prestigious colleges. Selection to the postgraduate courses (M.E. / M.Tech) in different universities is through an 'All India Combined Entrance exam' conducted by JNU, New Delhi, and to IIT's is through 'GATE'.

B.E/B.Tech courses are of 4 year's duration. The diploma courses are of 2-3 year's duration. Post Graduate course M.E/M.Tech is of 2 years duration. You can apply for any of the institutes if you have cleared the entrance exams that are kept in place for admission into various different universities.
