Hello Aspirant,

First of all based on previous year's cut-off trends we can help you with the expected qualifying cut-offs for this year :-

• Common Rank List (CRL) - 90- 95 Percentile
• GEN-EWS - 70- 75 Percentile
• Other Backward Classes (OBC-NCL) - 70- 75 Percentile
• Scheduled Caste (SC) - 50- 55 Percentile
• Scheduled Tribe (ST) - 40- 45 Percentile
• PwD - 1-2 Percentile

Now on the basis of above table and considering your category as Gen-EWS you holds decent chances to get qualified for JEE-Advance 2021 but still the official cut-offs are not out yet so it is little bit difficult to give you any confirmation.

Note that in above table it is not the actual cut-off for JEE-Main 2021 but expected on the basis of previous year's analysis. You can check out previous year's cut-off trends from the link given below :-

Now on such score as you hold good chances to qualify for JEE-Advance so  you should start preparation of JEE-Advance and if you prepare for JEE-Advance so you topics of JEE-Main will also get revised along with, so even if you do not get qualified for JEE-Advance (for which there are very less chances) then also you can appear for JEE-Main session 4.
