As the title stated, I'm currently looking for well recommended books that are good for self studying Geometry or Combinatorics (and Probability too) at a High School level. Before the school year starts in our country, I want to brush up and refine my math skills in those area for me to be ready, and also join some contests (mostly for Awards at the end of the year of our Senior Year). For additional context, some of the Competitions i want to join in this year are the TIMO, HKIMO, and PhiMO. I want books that cover a rage of topics from basics to specifics and such, while also good at teaching in my own pace.
