Lalania,
Help us understand the educational system in Canada....here in the states, you can either graduate from high school- which means you completed all the state's requirements- usually done through graduating from the 12th grade (though it is possible to not complete the 12th grade if you do summer school, and finish up earlier) or you can test for your General Equivelency Degree (your GED). With either you can get into college (tertiary education), though it might be a little more difficult with a GED...so, help us out, tell us what you are faced with in the North...
