well, college is 10000000% better than high school.
Had senioritis i remember the moment i was accepted at Univ of Florida, and thought, hell, why do all this bullsh*t when i already got in college....
but college man, is the best. Yeah, you need to get your act straight as soon as you get there, cause definetely classes are alot more work and difficult than college, but during college, look forward to road trips with friends, lots of single girls, being on your own, meeting lots of people..well, i don' tknow if you're the social type but even if you're shy and you meet the right people, college is the best experience man. Oh lots of free food, and lots of girls!!!
I know my first year i wasn't the most social being so perhaps it wasn't my best year, but then i met some really good people and i had a lot of fun, and developed my social skills a lot... and enjoy the easy life of high school while you can, but trust me, it will never ever come close to the college experience! Just be ready to study and have fun. They can both be done!
