do stay through the training, it's totally worth it! (Though it can get challenging at times)
I have to echo this sentiment. GeekU can be VERY challenging at times. It will make you want to tear out your hair, throw your computer out a window, and run screaming down the street.
However, it is more rewarding once you finish than I can begin to explain. The satisfaction you will feel when someone is so thankful to you... someone who was desperate and afraid... someone who depended on YOU in order to fix them up... yeah. It's just an amazing feeling.
