<p>" I’ll be honest now and say that I didn’t try as I should have in high school (still managed a very respectable GPA that got me in Penn) and therefore I’m not fully aware of my limits (I have an idea of them though), so I’m even more nervous with the pre-med route because I don’t know where’s my breaking point yet."</p>
<p>-here you have identified your weakest side yourself. You will have to change your work habits in college. Even people who worked very hard in HS for their grades, still have to work much harder in college. So, changing your work habits will definitely help. Otherwise, i do not know why you would not get GPA=3.6+ and MCAT=33+. Just ask yourself: others do it, why not me?</p>
