My son is a class of 2021 hopeful. He goes to a large public high school. He has completed Geometry Honors and Algebra 2 Honors (will complete in June). His school offers Pre-Calculus (Honors) and Calculus (AP) but no Trigonometry. How important is Trig for entrance to the USNA? Should he try and take an online course? I was hoping some of you could advise us the best course of action. He is currently a sophomore. Thank you!
