I know many people have asked the same question but just felt like doing one myself.

I am a junior this year, predicted distribution is 710770.

P1. Whacky sol using Bertrand’s. Hope the use of Bertrand’s doesn’t work against my favor

P2. Provided answer and construction (sigma (2i-100) * 100Ci )but without solid proof

P4. Standard sol with standard construction.

P5. Real neat solution using isogonal conjugates.

A friend at school also claims to have scored around 22 (he is strong as well, same predicted distrib as me, trig bashed p5).

Maybe the fact that a lot of people claim to have scored 22 will affect the other ongoing markets.

Another thing I was wondering about is whether p3 was solved by many: but perhaps this is outside the context of this market.
