Buyers Remorse

Within hours of making my final payment for the PMBR course, I am starting to regret it. Almost everyone I have talked to recently has said it was a waste of time because you simply do a bunch of MBE questions even though you don't know the law yet. How much can you honestly learn about your weaknesses if everything is a weakness? It sure seems like I am spending a lot of money to take tests that are easily available in the PMBR books for a much lower price. Still, I can't bring myself to cancel the payment. I am definitely suffering from pack mentality and will do just about anything to pass.
