I'm currently studying towards gaining my MCSE and have all of the MS press books. To be honest, i'm find it a challenge to read through all of them. However, i can get my hands on some Train Signal training videos, and just wanted peoples opinion on them. I've had a look at the site, and they seem to cover everything, but what i want to now is, is it actually possible to pass the exam and gain the necessary knowledge purely by just using these videos? I would have thought my chances were better, as you can actually see what's going on in the video, and try it at the same time using a virtual machine, but do these videos go into enough depth?
