Hey,

All medical universities and colleges require NEET entrance exam result, only on the basis of this, you'll get admission into any medical college.

From 2016, no state can conduct its own medical entrance exam, there is only one national level medical entrance exam for getting admission into medical and dental colleges and that is NEET(National eligibility and entrance test). And kcet also is not for MBBS admissions.

Check here about kcet as well -:

Hope it helps!
