How does one attain a 90+ average?

Question

I am going into grade 12 and now, every single mark counts. Just so you know, my average last year was 86. Basically, for the program i want to get into, i need at least a 91 average for the entire year. I've been telling this to my friends who do get 90+ averages, and they say that i cant do it because you need experience attaining those grades. Now, its not only a matter of getting into the program i want, but showing them that i can and will do anything i set my mind to. I want to know if anybody out there has some tips on getting this average, such as how to study ect. I usually procrastinate and avoid doing my homework.

Answer 1

"I usually procrastinate and avoid doing my homework."

I think that's a clue to your answer right there.

Answer 2

I'm not math genius, but I think if you get 90% correct, you would have a 90 average.
