One more thing I would like to add to this thread. There is a trick in Manhattan online test purchase. If you buy the online tests only, then you need to pay $40 (assuming no discount). But if you order a Manhattan "Sentence Correction GMAT Prep Guide", which costs $21, you will get the online Manhattan GMAT tests for
FREE !!!
Effectively you purchase the tests in $21 and get the guide too !!!
Moreover, if you can use a coupon too then that would be a cheery on the top
