Hello Shem!

The IISERs do not release any cutoff scores or ranks. But students generally analyse from the answer key and make prediction over the years.

Well according to the previous year trends, you probably can get a seat in IISER TVM(as last year, students who scored 80-85 got IISER TVM) in the first round or second round of allotment depending on the fact if its your 1st/2nd/3rd preference. If IISER Pune(generally, 100+ is required) is your first choice then you may not get get in the first three rounds...you may get other IISERs but can eventually use the float option to get IISER Pune. And you are also from the reserved category(If you belong to the non-creamy layers of OBC), so chances are good. You may also get IISER Mohali(A student scored 85 and got it in last round)and Kolkata(generally 95+ marks is required for general students). The newest IISERs too.

This year the IAT questions were difficult from the other previous year question papers. So, be hopeful that the closing rank may go down. And the seat intake from SCB stream has also increased by 25%. Also, the board cutoffs were relaxed to 60% this year due to the pandemic.

According to me, you will most probably get an IISER of your choice(IISER TVM surely). And you have the float option to get the IISERs of higher preference.

All the best!
