Dear Fellow Brilliant Members and Awesome staff, I would like to ask you all as to how to improve my mathematics skills especially in the topics Algebra, Geometry and Advanced Combinatorics. I am very weak at solving equations and also finding the maxima and minima using algebra. Rather, I would say I am not familiar with them( many level 4 problems are based on these). Brilliant Technique trainer unfortunately doesnt have good material for the above mentioned topics. When it comes to geometry, I am hopeless at proofs and would like to work on them. Combinatorics also is something where I lack a good base in. I would like to know about some resources for the above topics and also methods on how to improve on them and become like most of the Brilliant prodigies here! Thanks.
