- 12:33 - 13:32 - Problem 6
- 13:32 - 15:10 - Problem 7 (I screw up at the end)

- 53:50 - 56:20 - Problem 21
- 56:22 - 58:30 - Problem 22 (I miss a case)
- 58:43 - 1:04:14 - Problem 23 using Lagrange Multipliers
- 1:04:14 - 1:05:23 - I skip Problem 24
- 1:05:24 - 1:14:30 - Don't get an answer on Problem 25, so I go back to Problem 4
- 1:14:40 - 1:16:20 - I have no idea and guess wrong
- 1:16:20 - END OF AMC
- 1:16:36 - I grade it
- 1:17:25 - I go back to ponder about #4
- 1:18:35 - I ponder how I managed to get #7 wrong
- 1:20:00 - I calculate my score
- 1:21:08 - I figure out where I messed up on #22
- 1:22:48 - I figure out the actual way to do #23
Some notes:
- My laptop fan is loud.
- Apparently the timer only shows the actual time left when I go check on it. Probably a consequence of how Google manages resources, I'll think of a fix some day.
- Yes, I actually skipped #4 and then got it wrong.
- Yes, I actually used Lagrange Multipliers on #23.
- Note that I do spend a longer time on some problems than I should've, e.g. for #18.
A quick review:
- Overall a good test. Good representative of a "standard" AMC 12 in my opinion.
- #21 and #22 were ridiculously misplaced.
- #15 was strange...
I hope this gives people a sense of how I go about tackling an AMC. Enjoy!
