Hi,

The cutoff marks in IISER aptitude test is not released by the college authorities. So you can't be sure on it and it varies every year. However if you are a general candidate, you should get atleast 70 marks to secure a seat in IISER. I don't think at a score of 44, it would be possible to make it. You can read more about IISER cutoffs at this link-

Thank you.
