Write in vote for devoting time to actually work problems routinely. Ie every day, every other day, at least 3 days per week. It’s working problems and across topics that builds intuition and ability. Forgetting the book, but I have a book on solving problems which I studied from for the Putnam. The premise was to take someone seemingly around your level and build them up to problem solving machines. Probably math competition textbooks would be a good source for you.
