To check your KCET rank and see which college you can get as an ST category student, you first need your KCET result. Your rank will be based on both your KCET marks and your 2nd PUC marks. After the result is out, you will get a state rank, and this is the rank used in seat allotment. The all India rank is not used in KCET counselling.

Once you know your rank, you can use college predictor tools online by entering your rank and category to see which colleges are possible for your course preference like CSE.

If your rank is between 13000 to 30000 in ST category, you may get colleges like MS Ramaiah, PES University, Dayananda Sagar, BMS College or Siddaganga Institute of Technology. If your rank is higher like 60000 or more, you can still get CSE in colleges like BNMIT, BIT, Don Bosco or Acharya Institute of Technology.
