2021 AMC 12A Live Solve [Experimental New Format]

I tried to live solve the 2021 AMC 12A in 75 minutes. See how it went! (Spoilers below.)

The 2021 AMC12 problems can be found at (and were obtained from) https://artofproblemsolving.com/commu....


Among other inspirations, the idea of doing live solves came from Prof. Po-Shen Loh, who does this for viewer-submitted questions every week on his channel    / dailychallengewithposhenloh  .

With the inclusion of a timer, this was naturally more frenetic as compared to Prof. Loh's relatively laid-back sessions! Although I gave as much exposition as was reasonably possible at 3 mins/problem, some parts were obviously more messy. Let me know if you like/dislike this format, or have suggestions for any tweaks.

Spoiler: I completed 23 of 25 questions within the timeframe, failing to complete Q21 and Q24. I'll publish a follow-up video that explains Q19 and Q21-Q25 in a slower, more systematic manner.
