Yes, you should be slighty concerened, but not overly. I attended LMU and alot of people that I spoke to voiced concern over how good they were. Now, having passed all but one first time it is apparent that it is more your ability and desire to work very, very hard that is important. All the instructors were excellent, and willing to help out greatly.
However, a few classes beneath us had a few complaints. But, maybe they werent as willing to work as hard as we were.
