To summarize my life, I did undergrad in Canada graduated in Chemistry/Biology with a low and embarrassing GPA. Went to an offshore medical school for two years and once very unhappy- luckily I did very well there due to a change in attitude about academics. After much research I would like to go into biophysics. I have been looking into Canadian Universities - McMaster/York/etc and been discussing my options with several people. Since they will be looking at my academic scores from undergrad only. Since my GPA is way to low, I was wondering whether its worth it to take a full year of undergrad credits to offset my final year GPA.
