CBSE 12th

It's your choice if you balance between your school study and JEE preparation then you can start preparing for it in class 10th.

Hi Dushant,
Either mark sheets or academic transcript will be required in addition to other documents like your financial statements, etc.

Hi Harpreet,
You should consider working on your application. Your grades are fine though 66% is a little low for the universities. It depends where you applied in the past and on what basis you have been rejected. You must be careful of not choosing an irrelevant course. You must have had relevant subjects in class 12th and a strong quantitative background. Consider applying to another course, with a stronger SOP and recommendation letters.

By the way, your percentage is low. But do not worry, you can get admission in B.Sc., depends on the cut-off of the college.

Hi Aparna,
The eligibility is same as for DASA students. SAT is a requirement. You can check these on the official websites. I found this link for you, please check it along with your parents and try to understand what you have to do:

No not important !

Resonance is the best coaching institute for IIT followed by Allen and Bansal classes.

As per the criteria, you should have 60+ throughout in your academics, still hope for the best.

You stand a chance for sure. You have not mentioned about your CAT score, which may also be a requisite.
All the best.
