I graduated from high school early. (Score 1)

I am currently attending the university of Kentucky after graduating from a local high school before I was supposed to, recently after turning 17. I wish I could have taken a bunch of tests to determine how prepared I was for college instead of taking a couple classes over the summer. From personal experience I can say that I feel much better in college than high school, my gpa in high school was well lets just say low, while in college I am maintaining( and hopefully improving) on a 3.4, which is higher than the average. I am majoring in computer engineering and enjoy the classes I am in as opposed to high school where I just bothered to do well enough. Many of the lower level courses seem to review high school courses heavily, I wish I had been able to graduate earlier so I would only have had to learn it once. I also very much enjoy living on campus where I have many friends and many people are surprised when I tell them I am only 18 and a sophomore. My younger brother inspired by what I did graduated from high school at 16 and is also doing similarly, but on the other hand I have actually met other people who graduated early and are not doing nearly as well, being swept up in the social aspects of college, parties, and other such things.
