Hehe, I'm weird...I actually cook more now these days than I ever did before. But I've become a big fan of making a lot of something over the weekend and then my fiance and I eat it all week. I'd like to get on top of it enough to make a few different dishes over the weekend and then have some of each for during the week and put the rest of all of it in the freezer for later.
One thing to add...sure you can start stocking your freezer a bit ahead of school, but in the cooking department, things that you can do NOW that will help during school is to find recipes that you like and practice making them. It always takes me about 3x as long to make something the first few times that I make it, so I think cooking dishes you'll like that'll be your staples will help you be more efficient when school starts. Makes grocery shopping way easier, too (more familiar with recipes, ingredients, etc.).
Also, something that hasn't yet been said...if you cook, and cook extra, you will have left overs to bring to school during the week for lunch, which can be a huge money saver. Figuring out what to take to school on the fly every morning is tough so lots of people just buy lunch, which gets pricey. But grabbing some left overs, that's fairly easy. 🙂
Um, yea, but don't study unless you really really want to. Just have some fun, maybe earn some money. 🙂
