Hi,
You can get admission into engineering colleges through management quota if you have not written or cleared any entrance exam. But management quota is not available for government engineering colleges. Management quota is available for private colleges and private deemed universities. But through management quota the fee will be more than the actual fee of the college. You can get admission in any of the branch you wish through management quota.
Hope it helps!

Yes you can, for most of the B.A Degree courses the colleges don't have any entrance exam and for B.Sc or B.Com degree courses also there are no such entrace exams offered by most of the colleges. However for few courses like Microbiology, Biotechnology there can be entrance tests. However make sure that you follow the information brochure of the colleges where you wish to take admission.
Good luck!!
