I had to do this while sick and injured...BRUTAL. But this course WILL teach you the working skills of it. Just make sure to know how to set up your computer when you go to work and you're good.

Good course if you learn by definitions but horrible for learning hands on! You get zero hands on learning. It's all definition based learning! I give it one star. Nothing but videos and glossary based learning, no real time hands on stuff here!
