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.

As stated in the FAQ
We will only level you down if you keep getting problems incorrect over the course of 2 weeks. Don't worry; viewing and not answering problems will not cause you to level down, nor will taking a break from Brilliant. In general, we believe it is better for you to have a few easy questions, a few medium questions, and a bunch of questions that push you, rather than a whole problem set where you completely flounder.
We believe that students who want to take a vacation would still be interested in viewing the problems, and hence we do not penalize simply for viewing the problems. However, once you start answering problems, we no longer consider it as a 'vacation', and the leveling system takes over. I see that you have been consistently answering (at least 1) problems over the past few weeks, and getting several wrong resulted in the level down. If you didn't answer any of the questions, you would not have leveled down.
