Sample Olympiad Set


Do you want to practice for an Olympiad? Or perhaps you just got bored and (coincidentally) saw this? Whatever the reason may be, I hope you would try this out!

How it started:

I was recently in at least 22 contests this year, excluding my training. I was quite bummed out because I solve problems too slowly. If I do it fast, I will get a ton of careless mistakes. If I do it slow, I wouldn't finish the test in time. So I made these sample tests and I test myself a test every week. This is one of my sample tests just so that you will know how I do things here. Have fun!

More information:

This is like a test I do every week or so. I will collect 1515 to 1616 problems ranging from Level 33 to Level 55 and I will time myself for 44 to 55 hours. Depending on the difficulty (I can estimate their difficulties by looking at their levels).

Once you are done answering, compile all your answers and solutions. You should not change your answers anymore. Afterwards, input all you answers into the problem in here (Brilliant). In case your answer is wrong, even due to arithmetic errors, that is still considered as a mistake in the test, but you may input another answer in Brilliant after you have re-checked things.

And in case you have answered some problems already, try to shorten the time then. :P

If you would ask why they're problems made by other people, I do that to be fair. Because if that problem was posted by me, then I would already know the answer.

<Edit> I excluded B2B^2 problems because some of my friends don't have B2B^2 accounts.

For this test, there will be 1616 problems and a time limit of 55 hours will be given. Good Luck! :D

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
