If you take a look a the topic pages, you will notice that we've greatly streamlined the experience. Now, when you select "Take quiz", you will see the various concept quizzes that help you build an understanding of the chapter, and also a collection of the best challenges from the community. I encourage you to give these quizzes a try, especially if you are interested in learning more about the chapter.

For problem creators, we would appreciate your help in creating problems with missing challenge quizzes. In particular, the following chapters could use more Level 1 and 2 problems:

Basic Mathematics:Percentages

Algebra:Quadratic Discriminant, Polynomial Inequalities, Logarithmic Inequalities, Function Graphs, Rational Functions, Floor and ceiling functions

Geometry:Volume, Surface Area, Properties of Triangles, Similar Polygons, General Polygons, 3D Coordinate Geometry

Number Theory:Integer Sequences

Calculus:Polar Equations Calculus

Combinatorics:Data presentation, Distribution into Bins, Rectangular Grid Walk, Expected Value, Introduction to Recursion

Logic:Grid Puzzles, Arithmetic Puzzles

Computer Science:Objects, Complexity / Runtime Analysis, Sorting

Mechanics:Circular motion, Conservation of energy, Angular momentum, Rotational kinetic energy

E&M:Electric fields, Magnetic fields, Magnetic flux

Once we have numerous good problems in the chapter, we will curate a great challenge quiz which will be used to introduce other members to the chapter. Thus, your problems will have a high chance of being featured :)

I have shared 15 problems on Circular motion in this set: Circular Motion Practice. Most of the problems in the set are simple, but some are not!

Oh, that's a nice set :) I've added them to the list. Thanks!

Thanks! :)

I saw that all the problems have been added to the Uniform Circular Motion skill. However, not all problems have uniform circular motion. In some of the problems, the motion is non-uniform. We could add a skill for Non-uniform circular motion, in the chapter Circular Motion.

Great!

I did a few quizzes last night and I enjoy the new layout. The only area for improvement, in my opinion, is that upon completion there is no indicatior of what has been completed already when at the home list of quizzes. Since starting on Brilliant back in April, the site has undergone many great changes and I look forward to seeing how it develops even further. Thanks for all you folks do.

Thanks for that suggestion!

We are actively decoupling the quizzes from the list of wikis. We hope to present a list of distinct wikis related to the chapter, and then provide relevant quizzes for you to work on when exploring deeper. We will think about how to indicate quiz progress in a simple way.

This sounds certainly exciting! I will contribute to the logic section!

Woohoo!

Looking forward to that!

Request@Calvin Lin : I have posted various problems but they are not rated . Please help me out . Some problems of mine are waiting to be rated for more than month

Log in to reply

This comment is irrelevant to the discussion, and I will delete this thread soon. You can leave such comments on my message board instead.

As I've told you, problems are rated by

So, to ensure that your problems get rated, you can

1. Give it an initial seed level.

2. Make the problem good and interesting.

If you realize that a problem doesn't have an initial seed level, IE it says "level pending(10 points)", AND that it is a really interesting problem that the community loves (say > 100 views), you can mention me and I will assign a level accordingly.

If all of your problems say "level pending (100 points)", then it is a likely indication that they need to be improved on, in order to appeal to the community. Problem writing is a skill, which can be developed over time.
