Hello K.Sreedhar, firstly let me clear that if you appear for Consortium of Medical, Engineering and Dental colleges of Karnataka (COMEDK) UGET exam, you will get admission only into engineering colleges.
As this entrance exam no more provides for admission into medical colleges in Karnataka.

If you aspiring to pursue your career in medical, then appear for NEET, AIIMS MBBS and JIPMER MBBS.
NEET: https://www.google.com/amp/s/medicine.careers360.com/articles/neet-2019/amp

COMEDK UGET 2019 will be conducted for entrance into B.Tech degree programmes. There are 190 Institutes participating in the State of Karnataka.
It is an online Computer based test, and has approximately 20,000 seats available.

Well if you have already applied for the entrance examination, then it's great. Because the last date to submit the application was 19th April 2019, i.e., yesterday.

Also, a few things to keep in mind is that, the examination will be conducted on May 12, 2019.
And the results will be declared on May 27, 2019. The counseling for the same will start from the second week of July, 2019.

But most importantly, the mock test paper has been released by official website. Go check them out to get a good score in the examination, and pass with flying colours.
