Hello aspirant, hope you are doing good.

Firstly, it's really nice to see that you have your goal set in mind that you want to get into IISc, and even though it's really tough, I'm pretty sure you will give your best to get in. Now that you don't have much coaching centres near you, it's not a problem and shouldn't be an obstacle for your dream, you can get enrolled in online courses as well.

To get into IISC , you have mainly two options:

1. JEE Mains

2. KVPY

If you score really good in both, you have good chances of getting into IISC. For you, we have a knockout course for JEE Mains, that will prepare you well for your JEE Mains examination, and it's completely online. You can access the videos at any time you want, you can attend countless live sessions by well versed professors, there will be plenty of mock tests and other exams as well to assess you through your daily revision.
