hi,

admission to tamil nadu engineering colleges is done through TNEA counselling.  to admission in karnataka engineering colleges you may apply through  comedk uget. however seat reservation for other state candidates is less and it would be hard to secure government college if you can not able to bring a high score of 12th exam or entrance test. placement is based on individual colleges only. I would prefer to suggest for study on bangalore, there is many start up and good institute are located to learn about new technology and gain work experience.

hope you understand.
