JEE Advanced

Hello Submit,
With your percentile, you will most likely be clear to appear for JEE Advanced. But you will have to wait for the final announcement by National testing agency of the ranking released of the j e Mains examination conducted over two different time zones. They will be combining the percentile of these different sessions and forming a consolidated list with all India ranking. It is expected that first 300000 students will be allowed to appear for JEE Advanced.
Best wishes to you.

As there will be two JEE Mains exams this year, so after first exam only the percentile has been released right now. However, after the second exam that took place, everyone will know their ranks on the official website only. Thereafter, the marks needed to qualify will be disclosed after the second exam result that took place in this April.

Yes, you will qualify for JEE-Advance. Your expected rank is about 166666 and around 2.2 lacs candidates will qualify for JEE-Advance. Therefore, your chances are very high.

No problem, attempt the exam now.

If you are confident enough that you can study for one year without any diversion. Then yes you can. I am a dropper and I was self motivated to crack JEE with a very good score. And yes I did it. Everyone is capable of doing it, just don't lose hope and work hard for a year. The amount of effort should be much more than you put in 12th.
All the best.

You should improve your score in order to get eligible for JEE advance if you are a general category student.

JEE Advanced is specifically conducted by the IITs to admit students.

Sorry to say but its a no as IIT strictly says at least 75% in all subject mean above 75% or 75% not less than it and as you said you are from CBSE, then you won't came in top 20 percentile because top 20 percentile of CBSE is above 85%. So, you try in any other college.
All the best.
