hi,

see your percentage in 12th score is quite less and at this score it is quite difficult to get admission in any tier 1 college. also for placement in many mnc company in the final year of engineering , your academic score should be above of 60 percentage to become shortlisted for recruitment process. to get admission in tier 1 college you have to appear in entrance exams like jee main or state wise entrance test.

you may appear in TNEA counselling process where admission is based on 12th score.

hope you may understand.
