Should I wait?

I plan on using the resources at FedVTE to prepare for my A+ exam. The problem is that they currently only have 801/802 and not 901/902. I know there are differences in the material, but would it be a complete waste of time to study up on 801/802 and then do 901/902?

Some what yes. 800 series has win XP, parallel ports and other outdated things. Go get a 900 series book, youtube videos
