[Dan]

in? im a senior in highschool and i messed up my whole highschool...im an average student and i have a 2.2 gpa which sucks because i started not to care that much and did stupid stuff...well, im really interested in science especially biology but i hate physics...im goin to colleges undecided for now but i wanna choose my major after the first or second semester...i was thinking, wat if i get A's in my first semester OR second semester...should i go to pre-med coz im really interested and its the only thing i like...any advice or suggestions or even some majors to check out?? jus need opinions and wanted to know if pre-med is really that hard even if u put work into it? OR only smart nerds can do it...im an average student and just wondering and ALSO, im also scared that wat if i cant handle it anymore OR wat if i put in all that work but dont get into a med school????
