Sterling Test Prep

I have done the diagnostic tests up through 4 and noticed errors starting in diagnostic test 3; I have not gone back and carefully checked 1 and 2. There are typos (e.g. they 50 instead of 5.0) where the typo is in the correct choice, so you stare at the problem for 15 minutes... WASTING TIME. There there are problems where you just can't figure out how you are wrong... then you look at their solution, and they are solving a different problem (so their math/physics is just wrong). There is even a problem where their 'correct' choice doesn't match their own solution!!!

HOWEVER, then we run into issue 2: I have another prep book, highly rated... and it makes the problems in this book look like jokes. This is more like an AP Physics test prep than a GRE prep.

Only giving two stars, rather than one, for the fact that there are many questions with correct choices, answers, wording, etc. and --sadly-- I also needed the practice in e.g. geometric optics so this was not a complete waste of time.… (plus d'informations)
