Hard but worth it.

I primarily focused on the Quant side of things so this is where this review is going.

Quant: This is a product that really tests your math skills to the max. The questions are a LOT harder than regular GMAT questions and they test you on the absolute ends of the knowledge domain required for GMAT math. For example, with all sides of triangles known, is it possible to know the angles? The answer is YES => Sufficient.

Get this if you are aiming for a 45+ in Quant.

I'd also like to add that the format of the test mimics the GMAT really well. Even the colors are the same. That helps in putting you in an exam setting..if you will. Not a big thing but just another detail that I appreciate from GMAT club.
