Hi Priyanshu,

Congratulations on your amazing result!

According to your percentile, your probable General category rank is 6686 or 6687. This rank is subject to the total number of students who had apperared for the January session of the JEE Paper 2 and you can expect it to vary after the NTA releases the final result post the April session. You can use the following formula for future reference - 

Rank Predictor - (100-your percentile)x1,45,386/100

Where 1,45,386 is the total number of candidates that appeared for the January exam. This number will change when you calculate your final rank in April. Also, please let me know what category do you belong to so I can help you with the category based ranking. 

Coming to the prospective colleges, please let me know if you are aspiring for B.Arch or B.Planning so we can discuss the colleges accordingly. But also in the meanwhile, I advise you to go through our JEE Paper 2 -2019 article to get a clearer idea of the college cutoffs.
