How Long Will I Last?

Tonight was the first night of my Intro to animation with Maya class. Some time in the second hour I got totally lost. Then in the lab following class I got partially caught up.
Our teacher says we must spend 10-15 hours per week on the classwork to get anything useful out of the course. I don't know if I can put in that much, but, (owing to my many years of Harvard service) the class is free for me, so if I have to drop, it's no skin off my wallet.
