Do a high school co-op with the military. I did, during the second semester of grade 11. Walked away with my BMQ completed, a bunch of pay in my pocket, and 3 high school credits (some school boards assign credits differently, one person on my course got two credits, and another got 4). After the co-op is over, you have the option of going away for the summer to do your QL3 (your engineer training), where you will get more advanced training, more pay, and an awesome summer.
