I'm a high schooler and tend to take notes by typing out an outline of the important concepts in a textbook.
1) Would it be efficient to this in med school?
Everyone has a personal style, mine changes every week, but the thing that stays constant, is that I am a heavy text book studier. If this is your style, you might just carry it on into med school, but your studying habits will evolve as you continue through your education.
The one thing that didn't change for me, is that I still cannot go to lecture if my life depended on it. I don't get anything out of it at all, my attention span is too short in the morning. Watching the lecture on video and pausing it and paying attention to what and how the instructer says and emphasizes things and taking notes from that is pure gold.
2) How do you medical students take notes from a textbook?
I like to read a section and summarize what I just read and try to make up questions from what I understood. I have never been a good student in the sense of going to class, but I am damn good at identifying what can be asked and how it will be asked. I don't know how I do it, but I think its adaptation from having such a short attention span that I found ways to be effecient. I have always been a good test taker, so even if I know less than others, I seem to do better than them in putting 2 and 2 together to get a big picture and answer a question. I guess big picture is the only way to do it, because there are just too damn many details to memorize for memorizations sake without organizing them into a map.
3) Also (this might sound dumb) but is 5+ aps comparable to one year of med school?
Well, since your in high school and having such a heavy load at your level of education, I would consider it comparable. Sure medical school throws more at you than 15 ap courses can, it still sounds like you could compare it to that from your level of education. As you progress through school, you will learn how to handle more and more information. In conclusion, taking things from a reletivistic point of view, sure you can say relitave to you, its a good comparison.
Good job at taking all these AP courses . . . personally, I barely even graduated high school, let alone took anything compared to a college course at that level. My IQ at that point in time was somewhere between Hog excrement and not choking on your own drool. I think it has gone up to room temperature by now but i can't tell because Med school is similar to programming in Assembly. You gotta work real hard but think like an ape. The concepts are not that difficult at all, its just the amount of it.
In conclusion, Start thinking like an Ape and working your ass off J/k.
Good luck with everything and I hope all your dreams come true.
