Yes, for the IISER aptitude test, the biology section is compulsory for all candidates, including those from a computer science background. It's important to prepare for that section, as it will be part of the overall evaluation.
Hi,
Unfortunately, No, you cannot get admission to IISER through donation. Indian Institute of Science Education and Research, Pune is a premier institute with strict rules on entrance based admissions. The selection process is solely based solely on the candidate's performance in entrance exams like JEE Advanced, KVPY, or the IISER Aptitude Test (IAT). However, you can explore other colleges that take admission without an entrance exam.
