Dear Aspirant,

For the score of 63 your rank should be around 50k, and yes there is a separate rank list and admission quota for the students of Tamil Nadu, they would be more beneficial to take admission in Amrita.

As you have state quota still you won't get any seat here not even electrical/mechanical because of your low score, you need atleast 80 to get any seat here.

Cutoff for the ECE is around 18.5k or the score of something 90 to get admission here, now either you can take admission in other colleges or take admission in Amrita by giving donation and you can easily get ECE by donation. You can also appear in the 3rd phase to improve your score or wait for the year, now its totally up to you.

Best of Luck!!!
