The academic profile of the University of Tennessee's freshmen improved for the fifth year in a row, UT announced on Thursday. The class of 2012 arrives on campus with an average core grade-point average of 3.76 and a 26.6 average ACT score. Both scores are the highest ever for an entering class, according to UT. Students move in this weekend, and classes start Wednesday. Thirty-nine percent of this year's incoming freshmen had 4.0 averages in high school, compared with 32 percent last year. UT expects 4,200 freshmen this semester, and 87 percent of them are from Tennessee. Almost all of them have received Tennessee Education Lottery HOPE Scholarships.."
