Hi there,
Hope you are doing well.
with 655915 rank in JEE Mains, I am sorry but you won't be able to make it to AIT, Pune.
According to the previous year stats, the closing ranks for different streams were as follows:-
1) COE:-55132
2) ECE:- 87857
3) IT:-65295
4) Mechanical:-11326

So, clearly, you won't be able to make it as there is no reservation.
Hope it would help.
Thank You
