But yeah, changing schools & majors will definitely keep you from doing it in 4 years. At least you didn't say I did drugs & had sex! That's why a lot of the people at my school didn't graduate in 4 years. There was this dude that started school at the same time as me. When I was a junior, he was still a stinkin freshmen!!! But I was on a full scholarship that was only gonna pay for 4 years, so I had to get up & out. I took 18 credits/semester for 2 yeasr in a row, and I worked 2 jobs!
