Thank you all for your great advice!
So basically, what I'm gathering is that the general consensus is to take the minimum credit hours necessary during my first semester, and take the easiest courses/professors.
Now, don't get me wrong, I by no means intend to skate through college, but I want to minimize my study time so that I can devote as much time as possible to research/volunteer/extracurricular activities (and maybe get some partying in there every once in a while too hahaha). Taking only 12-15 hours sounds like a good plan.
I have no clue what the hell I want to major in. Another thing that factors into what I major in is the fact that Penn groups people together in dorms based on their major. If I major in something like biology or chemistry and am housed with a bunch of other premeds, what will life be like as opposed to me being the only premed living around other English majors? Are humanities majors easier than science majors? I'm the type of guy who can bull**** an epic paper hours before its due, btw....but this is highschool hahaha, i might not be able to get away with it in college.
And biology.....well it was so ridiculously easy the first time around that i didn't even bother to take the AP (had to choose either ap bio or ap chem) because all it was was reading the chapter and remembering what happened.....i might as well have been reading a novel but with a bunch of scientific vocab words lol. Bio tests were not too much more than reading comprehension tests. What's college bio like?
Oh, and another thing: I take AP Chemistry now, and I'm pretty confident that I am going to get a 5 on the AP test....now, if I do get a 5, then will I automatically get college credit for it or do I have the option to choose whether to apply that credit? I ask this because I hear that med schools do not take AP credit as a replacement for the prerequisites, so If I were to take the Chem AP test, then how would I fill the prerequisite in college? Take a higher level chemistry class? And if that is the case, will that be desirable? Or should I just not even take the chem AP test at all and re-take general chemistry (basically guaranteeing me an A)? I mean, I want to take the AP test because i feel like i have to prove that i can score well on college level stuff but i just don't want it to actually count for anything.
And I don't know if there's a major greek presence at penn but if so, and I joined, would it significantly cut into my research/extracurricular/volunteer time? And even if it did so a little bit, will the party time I gain be worth it?
