No, students extend the circuit by flying faster than Vy on climbout, taking a year and a day to trim on reaching circuit height, and failing to lookout before turning downwind causing the instructor to intervene and get them to continue crosswind until they have looked. With early circuit students it's important not to hurry them too much because they're already close to or beyond overload all the way round the circuit.
