please someone tell me which government colleges or universities best for bsc in computer science & their entrence exam?
See for most of the Government colleges/Universities the admission to Bsc in CS is offered in terms of 10+2 score merit. So there are not at all any national level entrances for the BSc CS. But there can be college specific entrances and to know about that you have to specify the name of the college in which you want to take admission and then we have to fetch out the admission procedure for that college.
Some of the top Government colleges for BSc Computer science:
Gandhigram Rural Institute, Dindigul
Osmania University, Hyderabad
Tamil Nadu Open University, Chennai
Cotton University Guwahati - Cotton College State University
