Police, If that works, it could be a difference between an "A" and a "B". I'll try it in the future for my CPA review to see if the recalling of material is improves. If pring can help you at least retain better, I think it'll be worth the time and money. Lets be honest, If one can regular read a book and get a 90 or above, there should be a lot of Summa Cum Laudes out there. The last time I check only .05% of an entire university graduate it with such high honors. So, If pring improves retention after regular reading, it has an "A" in my books. I will even recommend it to the members of the FIU accounting association.
