Science and mathematics: applying for science honors program at Columbia University

Essay on background and interest in science and mathematics (max 250 words)
Please help me with any grammar and punctuation as well as sentence structure. I also need to cut down some of the sentences because of my word limit of 250. Any suggestion of rewarding any sentence would be very helpful in this case. Thank You.

"Non-polar covalent bond?" that sounded Greek to me when I first heard it from my elder sister. Suddenly, I have started loving Greek when I started taking chemistry course in my school this year. Although sometimes easiest classes seemed tedious to me, science was never one of them. Sometimes I ask myself that where I got this interest from and I, most of the time come up with the same answer which is my father. I have seen my father studying science from my birth and the answer is easy because he is a doctor. My dad used to tell me and my sister how different parts of the body work, how certain medicine work, or even how he got diabetes, which is scary for both me and my sister since it is genetically transmitted disease!

As I have mentioned at the beginning that chemistry seemed to be harder for me, I considered biology as my best subject from middle school and now, this year I was startled to prove myself wrong through getting higher grades in chemistry than the grade I used to get in biology. Along with general science classes, the class I love is Science Research which allows an incredible way of learning to research as well as developing writing skills on science. Science requires great math skills and that also interests me just as much as science. I remember in 8th grade, my math teacher told me that I belong to honors class and deserve to take the high school course Algebra I and therefore he helped me to get into honors class and to take the advantage of having good skills in mathematics and that is the reason why I am still thankful to him till these days because he was the one helped me grow my interest in math.
