Try looking up the related wikis from here on Brilliant first , and then solve the corresponding questions i.e. from the Community Posts . This is the best option .

But if you are interested in advanced combinatorics , do the above mentioned things first , and start soving questions and learning new stuff side-by-side from , the Internet , Introductory Combinatorics by Richard Brualdi , A course in Combinatorics etc.

You'll get the names of the books from the IMO website where they suggest books for increasing problem solving techniques .

I've been doing Combinatorics for a while, even made it to level 5. But yet, I am completely blanked at those level 5 problems. Any wikis you have in mind to read up for them?
