Hii

Congratulations for your result. You have not mentioned the subject which you had applied for. Without that it is a bit difficult to give you the details about your query.. But i can provide you with the college predictor tool which you can use to predict the expected college.

You this to predict a college for yourself, remember there can be some variation as the predictor works as per the previous year information as the cutoffs for 2019 as yet to be announced.
You can check the previous year cutoffs from the following link - https://engineering.careers360.com/articles/gate-cutoff

Hope this helps
Thanks!
