im in high school and my grades are okay. im no einstein, although i have read many books on relativity. Im just not doing well in school, because i get bored and dont do the work. if i do the work, i get good grades, but sometime i forget some equations. my GPA for first semester sophomore year was 3.0 and im finishing my second semster in 7 weeks. if i got a 3.4, and tried really hard in junior and senior year, can i still become a particle physicist? also, im not so sure i want to be a particle physicist, im only 15 and have only studied a little into physics. Hell, when i started sophomore year i wanted to do something with chemistry, then i read all this physics stuff, and i changed my mind to physics. i know i want to do physics, but what is each sub topic like? P.S. what should i expect when going to college? i want to major in some form of physics, but am unsure which.
