Hello Rutik, 

According to the last 2 years, the cutoff for Your category for CS at PICT is just above your percentage by a little margin. Stiil you can hope and fill it during option forms.

Coming to VIT, according to last 2 year the cutoff is just below your percentage i.e it is 87.9% for CS (second shift). So, you can hope to get a seat at VIT for CS. 

Good Luck and make sure you fill proper choices during option form.

All the Best!!
