I am doing SYBSc in St. Xaviers with micro and chem as my subjects I have never studied psychology before so how do I apply for this stream?

I have given Maharashtra state board exam and have secured 83% in 10th and 81% in 12th.i am from a science background and have never had the subject psycho. So what are d basic requirements for clinical psychology? am I eligible for it? My college doesn't offer psycho with any science subject
