Canadian Grade 12 Marks

<p>Hi guys, I'm new to the form, it is great to have this nice resource for questions. If I violated any rules of this form, please inform me and I will watch myself :) </p>

<p>So, I am a grade 12 (senior) student at a Ontario High School. In Canada, the senior grades are reported 4 times in a year: Late November, February, March and June. Which means as for Jan. 1st, everything the american universities will receive is the November marks. (which is really really bad because many course only has a few evaluations, if I screw up a quiz or two, it's a difference between 95 and a 85...)
Therefore I wonder, are the Feb and March reports going to matter, if at all? </p>
