Dont be embarrassed, that too is my school. When I first went to college at UT, I was really intimidated by the Brentwood, Germantown, Farragut, and Signal Moutain kids who act like just because they went to weathy schools they are better or their high school education level is better. You are on a level playing field now. Where you came from means nothing.
I had a group project with 4 other students in a 400 level course my Sr year. Two of them were from Brentwood, one from Germantown, and the other was from inner city Memphis. The two from Brentwood and the one from Germantown had no clue what was going on with the project, didn't help at all, and after I told the professor at the end of the presentation that the Memphian and I did all the work, he promptly failed the 3, preventing them from passing the class, preventing at least 2 from graduation. Just shows, where you come from doesn't matter.
On a final note, find me a school with a prettier campus than Heritage. God's country
