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.

I think there are a lack of these, Brilliant definitely have a niche!

http://nrich.maths.org/secondary-upper can be quite interesting.

Udacity, coursera and edX sometimes offer maths/physics courses and a LOT of computer science. These courses tend to be more of a commitment than the style Brilliant offers. I love that I can come here with just 5-10 minutes and solve a problem or two. This site is so great!

Khan Academy.org is good! Lots of free videos to teach you how to do stuff, achievements and 5 levels for skills.Skills are less vague than in brilliant (100+ in Khan Academy) and practice is interactive (sometimes).
Some skill are easier than others.

I go on math.stackexchange.com sometimes to see what kind of questions people ask and, if I can, answer them. Helping people plus getting a share of math is always nice!

There are some really good study websites. Personally, I would recommend a reading review of edusson at https://essayyoda.com/review-of-edusson-com/ because this is a good example of a study website. If you will find other great resources, please write a comment below. It would be very useful. Thanks!

Hmm how is Alcumus a waste of time? Maybe consider changing your focus topic to something harder...it does depend on your level of math however. If you are past AIME level then you probably won't find Alcumus very useful unless you struggle with a particular topic.
