If you got around 60 marks in KCET and you belong to ST category, your KCET rank might be somewhere between 80,000 to 1,20,000. The exact rank also depends on your 2nd PUC (Class 12) marks, because KCET rank is calculated using both KCET marks and board marks.

With this rank and ST category, you have a good chance of getting CSE or other branches like ECE, EEE, or Civil in many decent engineering colleges in Karnataka. Some possible colleges where ST students with similar ranks have got CSE seats in past years are:

East West Institute of Technology, Bangalore
Don Bosco Institute of Technology, Bangalore
Acharya Institute of Technology, Bangalore
Bangalore Institute of Technology (may get non-CSE branches)
Siddaganga Institute of Technology, Tumkur (maybe non-CSE branches)
KLE Institute of Technology, Hubli
PES College of Engineering, Mandya
Malnad College of Engineering, Hassan
BGS Institute of Technology, Mandya
JSS Science and Technology University, Mysore (only in last rounds or other branches)

For CSE, the chances improve in lower-tier colleges or in later rounds. You can also consider IT or ECE if you don’t get CSE initially. Also, rural and newly established colleges will have lower cutoffs and more chances.

You will get a better idea once the KCET counselling starts and the cutoffs are released.
