I don't know if this will be helpful to you, Seng, but my experience with Personal Genius is that the results are almost never immediate. Usually, I'll listen one day, and the answers I'm seeking come either much later in the day or the next day. I wonder if you might have different results by listening the night before your lecture or test?
I have no suggestions for the memory CD; I haven't used it. (No, I didn't forget to use it, LOL)
