User blog:Deedlit11/Preparation for the next Googological Olympiad

So, I'm thinking of starting the next Googological Olympiad shortly, and I was wondering whether people had any comments regarding how it should be administered.

How long should I run it for?

Should I give immediate feedback, or wait until the competition is over?

If I give feedback, should I allow resubmission of solutions?

I was thinking of varying the number of points each question is worth. Is this a good or bad idea?

Thanks in advance for any comments!
