@AviSaxena33 Though you are junior, still it is not too late. The key is to understand what it takes to get selected for BS/MD programs and plan for the coming summer. That is the key. See the following links to get an idea of what students have done to get selected for BS/MD and what it takes. Academics, test scores, EC, you may already have. But the key area which you need to ensure you have taken care of is to demonstrate your passion and interest in medicine. If you have not done any thing towards that, you need to act NOW and line that up for coming summer.
Your interest in CS and Medicine is nice to have for 2 reasons. 1. In case later if you decide medicine is not your path you want to move forward, you have the plan B, which will enable to get a job. 2. Combination of these 2 fields really good to solve many problems, and it can compliment extensively.
There are many programs which does not need MCAT and all are highly competitive and selective. Example, Northwest, Brown, Rochester, Case, RPI, George Wash, Pitts.
