You can choose any subject of your choice. Studying with arts can also help you a lot for PC's.

Hi Veena,
candidates who have studied 10+2 with physics/mathematics, chemistry and biology/bio-technology as main subjects obtaining a minimum of 55% marks in aggregate of three subjects as well as 50% marks in English as an elective subject. So, yes you are eligible for chemistry honors B.Sc.
Hope this will help you.

The basic eligibility criterion needed to be fulfilled for admission to the course is a Higher Secondary (10+2) or equivalent qualification in the science stream from a recognized university with a minimum aggregate score of 50% at both levels.
But having biology or not will differ from college to college.

Yes, you can sit for the aptitude test. You should fulfil all other criteria for the exam. Go to the official website of IISER and kindly look over it.
All the best.
