Bunch of ripoff artists; ESPECIALLY MedStart - they claim 2 years access and then cut you off straight after UMAT day without warning.
Just scab resources off friends for free, and don't bother paying for UMAT "teachers" to show you the ropes. They're not all that great anyhow, seeing as most ppl use em and only around 10% actually come out on top (some of whom don't even prepare at all)
