HELLO AKSHAT

Since it becomes very difficult to predict the actual rank but we do have a backup we have a formula;l to calculate the expected rank that is (100 - total percentile ) x 112679/100. So your expected rank for the present percentile for january session comes out to be 1250.The expected rank might change depending on the no of candidates appearing the april session.
since the official cutoffs are yet to be decided let us analyse your chances by using previous year cutoffs.
SPA 2018
B.Arch General 7 - 414
B.Planning General 555 - 978

After looking into the data it seems a little difficult for you to enter this institute

No worries since you have an april attempt left.

But if you are curious to know that which college you might land into with your percentile then you can use the college predictor tool https://engineering.careers360.com/articles/jee-main-rank-predictor
BEST OF LUCK FOR APRIL!!
