I'd give 3.5 - 4 stars for the paid service PrepAgent offers. Joe has a knack for teaching! I originally found his videos on YouTube and then joined PrepAgent.
There are several ares (on the National side) that there was little to no information on in the form of videos. Some content was incorrect. On the State specific side (I'm in AZ) the depth of information was lacking considerably. That all being said, i passed my schools exams first try and went on to pass out state exams first try as well. I would recommend PA, however, i think there are areas for improvement in the video content that would add considerable value for future customers.
