Using My Potential as a Student

I'm not the type of person who gets good grades without effort. On the flip side, I'm also not the kind of person who studies all the time. I'm the type of person who can easily grasp onto subjects once I take a little time to go over them. I've always had the potential to be a great student but I've never really used it.

This year, however, since I'm in my last year of high school I've decided to put in as much effort as I can to get the best grades possible. Since I'm aiming to go to university, that means not only do I need the grades to get accepted but I also need the grades to be able to receive academic scholarships. It's only been a couple of weeks and I've yet to see any grades but I feel like things are going well. 

It seems to be that in my school career my grades tend to get better and better each year. Especially since I've been in high school I've noticed my marks increasing each year. I think this is mainly because when a subject bores me or is too easy I won't put in any effort but when subjects become more challenging I enjoy them more and put in more effort. Basically the contrast between a class like math and a class like English. Although I'm naturally better at English I achieve a better mark in math because it's something I have to work for whereas English I can pass without doing anything.
