AMC 12

I think I did pretty well. There were two problems that bothered me though:

#15 - I made a really stupid mistake. 6 points down the drain...
#25 - I thought I had it, but turns out that my logic was off. Afterward, I was able to bash it out with a calculator to find the right answer. I'm curious as to what the efficient method is. I did recognize that it was clearly a tangent sum, though. I would've hoped that the answers would give me some "guessing credit," but I "GUESS" not.

I didn't answer 23 or 24 because they stumped me. xD

Everything else, I'm pretty sure that I got right. So my score should come to a 129, more than enough to make AIME. Hopefully, it'll be enough to help me make USAMO later.

Here's the coolest video on my mind right now:
