Hello. Since percentile largely depends on the total no. of students appearing in the April session of JEE Mains 2019 therefore it is difficult to predict exactly which college you will get.

But based on your current percentile your probable rank can be around 23433. Your category rank cannot be predicted now so you might have to wait till April for that. But as per previous years record if your category rank is 1000 or below you may get a good college for B.Arch.

Based on your rank you can also check the below link for your college prediction.

Hope this helps. Good luck!
