Hey Keerthikumar, all the undergraduate colleges for first year starts by the end ofJuly. RNSIT Bangalore usually begins its class from the first week of August. Normally all Bangalore colleges starts from August only. Try not to be absent during your first week of college because in colleges it hardly take two three days to form a good bond and group. And be prepared because college is not like schools so try and enjoy every moment of your college life .

Best wishes
