TopNewestAs you do problems on Brilliant, pay attention to the types of problems you consistently miss or underperform at. Try to learn from the featured solutions, posted when problem sets expire. We will not post or discuss the current weeks problems in this forum. If you find that there are specific topics that you would like help understanding, ask the forum. We may be able to help you or point you to other online resources. Also, you may suggest for Calvin to write a "key techniques" post on a topic that you would like to learn more about.
