I'm a Canadian undergrad hoping to go to a US DO school. My first two years of undergrad were pretty bad (dealt with some personal issues,etc). I've repeated about 6 courses (that are pre-reqs) and went from Ds/Fs to As/Bs. Have my chances of being accepted decreased because I repeated many courses. Also, I repeated one course twice, so how will the committees look at that? Will they just simply count the highest/recent grade in the cgpa? Thank you for the advice and support!
