Yes, you can get admission to the IISER with 6000 rank. However, admission will depend on your category. SC/ST category students have a strong chance of admisison with the mentioned rank. General category students can get admission to the newly added IISER.

In such a situation, you have to prioritise which exam you want to appear for. You might have prepared for months for the exam. Based on your preparation, you have to decide which exam you can easily qualify for and get admission to the desired course and college.
