Sure you can get into b-school... just depends what you are aiming for. If you are applying T-10 it's going to be really difficult to argue why you can't score better. There are a number of posts here that address that so you can use the search function. Otherwise, I would strongly suggest enrolling in a course if you haven't (I personally suggest Manhattan GMAT
) to prepare for the GMAT. Otherwise, if you aren't shooting for a T-10 type school and you have a solid background, GPA, work experience, EC's, then you may still have a good shot.
