Hey aspirant ,
Glad you are aiming high . As per your query , yes you can get admission into iiser , provided you qualify the entrance exam . The shortlisting process doesn't take into account board marks . Only after clearing the entrance exam you become eligible for counseling . Here am going to provide you the details regarding the criteria and processes , which will further more clarify your doubts .
Candidates can apply for IISER through

• SCB ( state and central board )
• KVPY stream .
• JEE ( Advanced ) stream

The application form is available onlinr for all the streams . And the exam dates are also different depending on the stream .
One has to submit 1500/- ( general ) as a part of application fee . For reserved category 750/- (SC/ST)
.
Elligibility criteria :
KVPY STREAM :
One should have the valid KVPY. Scholarship certificate starting from 2019-2020 .
JEE ADVANCED STREAM :
one should have cleared JEE ADVANCED EXAM with a rank within 10000 ( general rank ) .
SCB :
Candidates must have passed 12th (science) .

More information :

• Exam mode is online mode
• Duration 3 hours
• Multiple choice questions
• 3 mark for correct answer and -1 for incorrect .
• Physics , chemistry , mathematics , biology as the subjects under the exam
• Each subject will have 15 number of questions each .

The syllabus and study basis are available in PDF format too . If you did not have mathematics as a subject , this prevents you from applying for the exam . A percentage of 90 cannot bag you a seat in IISER unless you qualify the apptitude test .

.I hope the said Information has been helpful for you to understand regarding IISER exam . For any further queries feel free to ask in the comment section below .

All the best
Thank you.
