<p>There certainly are options - each case is an individual one. Whether academic standards are not met (GPA too low) or a class is failed then there are several routes.
STAP - summer school is offered and a failed class can sometimes be made up in the summer.
Additionally the academy has the option of “turning back” a cadet, especially a plebe or separation.
Some cadets who are separated are invited to reapply, do so and readmitted.</p>
