Sometimes by design, overlap occurs between courses. Intentional overlap is designed to represent two aspects of a particular concept and serves to connect the whole with its parts. Demonstration and computer generated labs are discouraged. For example, upon completion of the Avian Physiology course students could take blood from the jugular vein of a day-old chick with the ease equal to an experienced veterinarian taking blood from a cow. This is as good as its instructors.
Problem solving situations keep the students minds active.
It could be on the part of the instructors as well as the students. Four instructors per course seems to work out well. A varied interactive course structure seems to work well. A written student commitment to the program and a written summary of why the student wants to attend this program is a must. Students attending with a purpose have a higher degree of success within the program.
