As I told you before, SMP is your LAST CHANCE. Don't even attempt to begin one until you're stable and can handle academics unlike what your current transcript shows. I know I am being blunt, but if you blow an SMP, that's gameover. It'll show two things: 1. You cannot handle a medical curriculum 2. You cannot make an accurate judgement call and took on something when you weren't ready to.
So just do yourself a favor, hold off on the SMP.
