Perhaps Im really bad at googling. I've participated in a rated contest just now (https://mathdash.com/contest/quant-4) to try out this website and Im really confused at the rules of the contests.

I've only been able to find https://mathdash.com/contest-rules for rules. But here are some more rules which I am not sure of

  • what answer format is allowed? It seems simple expressions like 23/3 and 10+6.5 are allowed. Is there is a full list of such allowed expressions?
  • what tools are we allowed to use? calculator? Surely I would assume using python is not allowed

    Hey — Sorry about the confusion — just added an announcement banner in every contest that should explain general rules!

    To answer your questions: Answer the problems without calculators or external aids. Answer format should be expressed in simplest form (e.g., '1/2', '2sqrt2', 'pi/3 + 1/7'). Multiple choice answers should be a single letter ('A' or 'a'). Simple expressions may parse correctly, but if they aren't in simplest form, the contest author may decide to consider them incorrect.

      What's a point of maintaining rules for which it's not possible to verify if they are followed by participants?

AkshajK can you please kindly explain this here? Union = both areas summed = 1 + 1, right?

Never mind, I figured it out. Union = A + B — intersection.

Spoiler

Also, are there editorials for these problems that are accessible before you solve them?

is it just me or is it funny that the bigtime quant firm chose the name Aaron instead of Alice?

AkshajK The timing for some of these sponsored contests is a bit early for west coast users; any chance they could be moved back an hour or two?
