Hello Abhi

6000 is a good rank in kcet. Since you have not mentioned it I will assume you are from Karnataka itself and from general category. To get Btech in Computer Science from KCET in PES you need to have  a rank within 1500 (general category)  hence I think it will not be possible in your rank but you can get a lot of other good colleges like MS Ramiah, Dr. Ambedkar (for CS).
