Well
I know Greg since the very beginning, the early days.
I think he is a great tutor with great contents and on top of that he came out with a formula NOT innovative but very effective: pay few bucks for great contents
I reckon he is in the middle of a classic prep company such as TTP or
magoosh and a pure forum based website like this
His website has its own DNA. like us.
The great thing about Greg is that concepts are discerned until you have nausea, from every angle, over and over again..........maybe a bit redundant in the end but definitely great things he is doing.
