Average PSAT scores for Texas Juniors?

That depends on whether or not your school runs on a 4.0 scale. If your school does, then you are definitely fine as long as you stick with that. Texas A&M allows automatic admission for students in the top 10% of their cl and students that meet SAT requirements and are in the top 25% of their cl. If you get the same score on your SAT (which is likely) and make sure you stay in the top quarter of your cl, then you should have no trouble getting into A&M.
