Dude 1900-2200 is great. I got a 2170 and I got into one of the top universities in Canada. You should be fine.mostly because the topic is inherently uninteresting
that said, on topic:
I'm stressing about the SAT. I just took a practice test and got somewhere between a 1900 (bad) and a 2200 (acceptable). (They only give you ranges because different forms have different areas weighted differently)
I have almost no extra-curriculars, no community service, and my grades are fairly average (although I take demanding courses), so my SAT score is my main selling point for getting into college. The test is March 1st. I'm worried.
Once in high school I attempted to stay awake as long as possible just for the hell of it. I lasted four days and three nights before I succumbed.
Once I went for a fortnight using the following pattern at night:
stay awake for 2 hours
cat nap for 15 mins
another 2 hours awake
15 mins more...
...and so on and so forth.
I got up to date with all my work, finished writing a 40k codex, leveled a WoW character to 70 and finished painting an army, but, goddamn, I felt so shit for the entire period.
