I'd say that sounds quite cheap for 10 weeks. I did a 1 day (about 4 hrs) chocolate course once and that was about £60 but they provided all the chocolate we were working with. Maybe check exactly what they provide and what you are expected to bring? If they provide all the fondant etc, I'd say it's a bargain! It's difficult for long courses if you are self taught because there will inevitably be things you already know that are repeated so you have to work out if the stuff left over that you want to learn is worth it. Even still, the instructor may show different ways of doing things which make your life easier!
Hope you enjoy it :-) x
