Ok, so here's my situation.

My final mark in advanced functions was an 80. The reason it was so low was only because of one test I wrote (14%). My teacher said if I did well on the exam he's be able to omit the test from my mark. So I studied my arse off for 5 days straight and still managed to do much worse than anticipated on the exam, getting a 86%. So my teacher decides instead of omitting the test, he just gives me an extra percent on my final mark (thanks a lot!).

So I'm trying to decided whether I should retake the course in my grade 12 year. Normally this wouldn't be a problem, but I want to go to computer engineering at waterloo. They say "individual selection from mid 80s" will get in. I understand though that If I retake the course, they will subtract 1% from my admission average which would be equivalent to 6% from my course mark.

I'm thinking I should retake it in my grade 12 year, but I'm not too sure how much i can bring up that mark....

So I went back and talked with my teacher a bit, and he was able to change my mark to an 86% !

Lesson to be learned here:

Always go back and negotiate until you get what you want.

I hate people those chronic mark-beggars. My class was littered with spoiled kids who would moan and groan until the weak teachers thought it was either they had to give a higher mark, or shoot themselves.

Try begging for more marks all the time and see what'll happen later in life. 5 years from now your boss is not going to give you a raise just to shut you up.
