but would like to know how in a day i could walk out having passed airlaw for instance
When my PPL lapsed, I had to take the CAR exam. I hadn't looked at air law for years. I found a free online resource that contained all the FAA CAR questions and rotated them. I spent an afternoon quizzing myself until I knew them all.
Got 97 % I seem to recall. Get googling...
Best,
SSS
