Okay, I know nothing about Sqaure 1. Whats a good method to get sub 20? And how hard is sub 20? And a good tutorial. Thanks. Ill of course do my own research. Just want to see what you guys say.
You don't need many algs to be sub-20 though. I probably know around 10-15 total and I've averaged 19 for the past year or so.
