Hello aspirant,

Indian Institute of Science Education & Research administers admission through various channels - JEE, SCB and KVPY. The authorities administer IISER aptitude test for admission by SCB channel while KVPY and JEE Advanced qualified applicants will not be required to appear for the exam. For fulfilling eligibility for SCB, candidates have to pass 10+2 level with science stream and should qualify the cut off marks which are announced by the concerned authority. So first candidates aspiring for IISER must check the eligibility criteria specified by the concerned authorities.

Hope this helps,

All the Best!!
