to add-on to Jochangy, it's an all-around thing. Jochangy said he was upset with his academics, but his extracurriculars were outstanding. On the same token, however, being one-sided does nothing towards admission to West Point. They're looking for well-rounded candidates who challenges themselves and succeeds wherever they may go. On average, something like 95% of incoming cadets participated in a sport at the varsity level. Just under 60% were captains in at least one sport.
You asked for transcript though so I assume you're particularly asking about the academic portion...
West Point makes an effort to look at how competitive you are against your peers at your school. Thus, your class rank is the #1 academic factor. GPAs are so unique from school to school, they're value is slightly diminished. SATs and ACTs are 2nd behind class rank because they remove all excuses and pit every candidate equally against every other. In terms of honors, APs, special programs... the competitive nature at West Point suggests that if you're choosing between taking the easier course and getting a 97 or taking the harder one and risking a B take the harder one. Compete. Compete. Compete.
