Hey Raanan!
I just turned 19, not much older than you. I am majoring in electrical engineering. The physics class I'm taking is one of the required courses for engineering, of course. I chose electrical engineering because I'd love to be able to design and build electronic machinery, especially robots. I'd like to get into robotics. I have been interested in that sort of stuff, incluidng radio-controlled stuff (in which I take great delight!) since when I was in 3rd or 4th grade. The other courses I'm taking right now are general psychology, american literature, and ultimate frisbee (a lot of fun!). You don't have to choose your major in your freshman year. As you take courses in college, you will have a better idea of what you want to major in.
Good luck and God bless!
