wow. i just found out that my friend got in last year while having a 69 in bio

All I gotta say is try hard. Because admission's will be raised this year as more students are applying.

Don't worry about it. If you make the cut-off, you're in. That's why it's called the cut off. They don't compare applicants with other applicants. They only thing they do is they take all the applicants marks and determine a cut-off from all those marks. So if make the cut-off, you've technically been compared to other applicants and succeeded.
