hi sir/mam i am pcm student and i got 62.2% in 12th class.can i try to medical courses??

Sandeep, to study any Medical course, you need to have studied Biology in your 12th. For example for NEET which is the entrance examination for admission to Medical, Dental, Ayush and Veterinary courses, you should have studied Physics, Chemistry and Biology. You can also study Biology as an additional subject to be eligible for these courses. Now these are the major medical courses. There are other paramedical courses but they do require Biology as a core subject and not an additional subject. Please visit this page to check the list of Medical courses that you can pursue after 12th: http://cbse.nic.in/newsite/attach/Compendium%20of%20Courses%20after%20+2.pdf
