You don't say what the course is about. Is it a bushcrafty thing or is it a course where you'll be spending 10 hours doing something else after which you have to make your own food. What I mean is: Will the cooking be just to feed you or as part of a social thing with your course mates?
Anyway here's my opinion. The Jetboil is really light and very efficient. Tonight I heated up a curry and rice (precooked twin pack thing from the supermarket) plus a large coffee on 8 grams of gas. The standard (small) Jetboil cannister holds 125g. So for a week, two cannisters, or one large one, would be more than enough. The Jetboil is very quick, so if you have a 15 minute break in the course you can brew up no problem and get back to whatever it is you're supposed to be learning. But it really is only good at heating up water; I wouldn't cook pasta in in, for example. So you'd be stuck with food you either rehydrate or warm up.
I've also got a stainless steel Trangia, which is at least 4 times heavier, even before you add the fuel. But it has a kettle for dedicated water boiling, two pots for pasta plus sauce, a plate for serving or eating, plus room for pot cleaning things. I can bake with it too.
For a trip where I'm just serving just my own needs and weight and convenience is a factor I prefer the Jetboil. For real "cooking", or providing for more than one person the Trangia pays off.
