I might get the following books
1. 113 geo inequalities
2. 109 inequalities
3. lemmas in oly geo
4. 112 combo
If anyone has experiences with 112 combo can you comment or smth?
I can solve most combo problems up to Aime 10 and some of the final five rn, and I will be done with cops inter combo (both book and class) soon. Should I get this for late Aime-early oly?
Im not sure about the level of this book and I couldn't find much about it online so...
