My son attends high school in Maryland. He has a 4.86 weighted GPA with one B and will likely be first in his class. He had taken 7 AP classes through 11th grade. His highest SAT score was 1440 and his highest individual scores were 740 in both math and English. He played a varsity sport 4 years, was the captain of an academic team and is generally well-rounded.
Texas takes 90% of their students from instate. While your son’s stats are great, an OOS applicant vying for a popular major makes it a reach.
