Hello Aspirant

The Indian Institute of Science Education and Research(IISERs) are a group of premier science education and research institutes in India. These institutions have been declared by an Act of Parliament as Institutes of National Importance and are intended to be the leading institutes in the country in the field of basic sciences. These institutes were created by the Government of India, through the Ministry of Human Resource Development.

There are seven IISERs across India

1.    Kolkata

2.    Pune

3.    Mohali

4.    Bhopal

5.    Thiruvananthapuram

6.    Berhampur

7.    Tirupati

If you have scored 100 marks then you have a chance of getting a chance in second counseling. It also depends on the highest scores that have gone for that year. As mostly the top 200 students are selected.

It is also likely that you can get admission in IISER Berhampur or Tirupati as Mohali is a bit difficult to get with this score.

If you have availed the “Float” option, and if luck is on your side, then if not in the first round of allocations, maybe by the second round or third, you could have a shot at an IISER preferred by you - though this is highly unpredictable.

There is still a chance for you to get into atleast one of the IISER. IISER Pune is the most difficult one to get into. The newer ones - Berhampur or Tirupati - have a higher chance getting into. 

Best of Luck!
