An okay test to build your stamina

The Global expert test has 15 test, I think this is enough to give you the mental stamina on test-day. At just $50.00 — price is very reasonable (got mine from a competition though)
Now you get a detailed analysis of your weak and strong spot per test (that’s awesome) and interface is similar to GMAT’s: that blue and white stuff
Quant questions and scoring are good and to have an idea of what your Quant score might be just average all Quant score for the 15 test you took, you will know your stand (quite accurate )
Verbal questions and scoring ain’t bad — pinpointing your weakness ,but needs thorough improvement in other aspects
Overall a good product worth the $50.00
Hope my review will influence your decision
All the best :)
