Ｍｙ Interest in PC

I have had interested in PC since my high school age. In those days, some of my friends could computer well, and I was a little enviable that. However, my school did not have lesson on computer, so I could not study. Also, I have more one reason. I want to study science in university. In that field, what I can use computer is essantial thing. Therefore, I want to become well on computer.
