It is possible for you to get into MD schools. You need to do some research and apply accordingly. Some schools admit students having scores as low as 24 but I guess it also depends on your ECs and other stuff. Some schools also look at the individual scores. Like for e.g if english is your 2nd language and you are a minority, they could probably take that into consideration. Of course, the higher the score, more your chances but don't give up. 26/27 is average score of MD applicants. ANd you don't have to get into the best schools.
