No. It's not too late to apply. I can speak for TCOM only though. I put my application in late Dec, early Jan, which I can't recall precisely since it's been a few years. Was interviewed in April, accepted one week later. Your MCAT score is fine for DO school, just need to get past that 7 for the verval. Ideal is 9 across. However, if out of state, you need slightly more competitive numbers than 9 subsection for more competitive schools. Go ahead and apply.
