i know its possible to get into a four year university after being expelled. They also do not look at your freshmen grades with a whole lot of wieght. If you go through the rest of your high school career and try hard, you can easily still do it. I advise taking alot of Honors and A.P. classes if you can. They bring your gpa up one point and are basically the same material only with better teachers and a little faster paced, but its nothing any idiot can't do if they are willing to dedicate the right amount of time. just try to be serious about school while still having fun. my first few years of highschool it seemed that grades/fun was a trade off which i found out later was not true at all. I got a 4.0 first semester of senior year, did basically no homework, and was drunk and/or high basically every night. Highschool is nothing more than a semi-corupt system that can be beat easily without you needing to put alot of effort forth, you just have to figure out how to beat it. AP and Honors classes were key for me, may be different for you but i can gaurantee its possible to get out of highschool without trying terribly hard. Make sure you don't skip out on your education though. I used to always come home and read about shit to get my real education online. I only read what i cared to know. I also tried hard in some classes like gov and film where i actually cared about the subject material. they tried to not let me into AP classes cause i got B's in regular classes but i got a letter of insistance written and then i turned out to be one of the best students in gov while still being high in that class and hung over. I say you can do it, just gotta be willing to try.
