My continuous learning and my obsession of achieving the best and becoming rank number 1 in my school, never really allowed me to know which subjects I have excelled most, but I guess the medals I got at the end of the school year revealed which courses I excelled most.
^You used "excelled most" twice, it sounds awkward. Are you really #1 in your school? And you sound kind of arrogant when you say that you're so good that you don't know what you're good at most.
I viewed each course as different steps I have to achieve to reach my goals. I have excelled in math and science the most.
^again with "the most" and the first sentence is random.
These two classes gave me an excuse to come to school everyday.
^an excuse to come to school? does that mean that you wouldn't go to school if you did not have these two subjects in your schedule?
Math is an easy but complex course to learn. It is complex it take more solving skills and adding a few extra steps to get the right answer. In other words it is simple because it takes only a few steps for people to do to be victorious with the answer.
^I'm thoroughly confused by this. I don't think that you need these general statements. Everybody knows what math is like.
Math was never my favorite subject. When I was in Ghana, I would be among the bottom 5. I had such a hard time with the class all the time and I used to say to myself that I was doing my best and my best got me in the bottom 5. I was in boarding school so I did not have any parent to help me with my assignment. My best friend on the other hand was among the top 5.
^Placing such emphasis on your placement amongst your peers does not demonstrate a lust for knowledge but rather a desire for unessential status.
My math teacher was not helpful. He would scream and make fun of me every time.
^unnecessary
Another liberal class I enjoyed learning and excelled was chemistry. The study of substances and the interactions between the different types of matter, especially electrons and understanding the way everything around us works fascinated me.
^You can't just add something randomly as an afternote. You mentioned science before and yet you did not explain that. Either expand it or delete it.
