I'm enrolled in the Online prep for step 1 I had no trouble using it until two days ago, the video that I was playing begin to lag, and today I can't even play through a whole video! It just kept stopping and loading and playing and stopping... every 10 seconds or so!! I looked at my internet connection, there seem to be no problem, I tested my download speed was at 150~300 Kb/sec! No way it's my internet connection problem! I online chatted with a rep to ask if there's any server problem and he said "that that I know of" and didn't even offer me that he'll go check or something Well, if I ought to get THAT kind of lousy response I wouldn't even bother writing! Anyone having the same problem? Don't use Online prep if you're considering to buy Kaplan or not, it'll drive you crazy!!
