Level One is the equivalent of an undergraduate major in Medical Astrology.  You can think of the prequisites as the freshman and sophomore years in which you learn the vocabulary and meanings of the signs, planets, houses, aspects, and calculations for the natal and progressed charts and perhaps a little bit more such as astronomy and details about precession of the equinoxes and the reason we have both sidereal and tropical positions for each planet and sign. 

By the junior and senior years, you prepare for a career.  Compare the junior year to the interpretation of stress in all the various ways that stress is shown such as hard aspects, relationships to malefics, 12th house placements, and new techniques such as the first wound and astrological interpretations of psychological stress tests.
