Not necessarily - the answer to this question depends on the individual student. There are many students at Notre Dame that balance very rigorous academic schedules, including AP courses, with debate. It is easy to balance your schedule with the Introduction to Debate course, but it requires learning to balance and discipline yourself.
Additionally, ALL students who have been in debate even for one year have said the course greatly improved their confidence and skill level in public speaking, critical thinking, and research. They felt that after taking Introduction to Debate and going to a couple tournaments they were more prepared than many of their peers to complete research papers and make presentations in class.
