Hello aspirant

You have got 89.66 percentile , with this percentile your expected all India rank will be around 89855.634

If you are from general category then you are at border line as 2019 cut off for qualifying Jee main was 89.7548849 But cut off varies every year . Usually you should get 50- 75 marks more this year. Let's wait and see Jee main July results. Results are unpredictable this year due to lockdown. Cut off depends on number of candidates appeared and qualified, difficulty level of exam, previous year's cut off etc.

Cut off can decrease from last year's cut off or remain same so you have chances for IIT colleges but which branch you will get it can't be said now.
