It's no longer a secret.
Most seminars take place on the weekend.
Typically they begin at 8 a.m., pause for a one-hour lunch break, then continue until 5 p.m. Students are usually given at least a pair of 15-minute stretch breaks. Participants are asked to take hourly quizzes to verify their presence. At the completion of the seminar, students are then given essay questions to complete. The one-day seminars require completing six of twelve questions.
