TNEA

It's not easy to calculate your TNEA (Tamil Nadu Engineering Admissions) rank based just on your 12th CBSE scores (160), as TNEA ranks are established by a normalisation method that takes into account all candidates' performance in addition to your 12th marks. The precise ranking is determined by the total number of candidates, their grades, and the authorities' normalisation algorithm, which varies annually. A CBSE score of 160 is typically regarded as normal to above average. You would need to be aware of the whole score distribution and the normalisation process for the TNEA exam given in that specific year in order to obtain a more precise estimate.

Of course, you can take admission at SA Engineering College for B.Tech without the TNEA (Tamil Nadu Engineering Admissions) process. Candidates are admitted based on their eligibility criteria that are set by the college, namely passing the 10+2 (HSC Academic or equivalent) examination with the minimum required aggregate marks in Physics, Chemistry, and Mathematics. For OC, the minimum aggregate mark requirement is 45%.
Moreover, the applicants who have achieved a 10+3 or 12+2 years Diploma or B.Sc. with Mathematics as a major subject can apply also. The minimum aggregate marks requirements in this case differ: 55% for OC, 50% for BC/BCM, and 45% for MBC/DNC/SC/SCA/ST categories.
