Just to add, while it is not just having a Progress Test being done by an appropriate examiner but the core phase also needs to cover the all the content as a PPL; as all MPL courses are different then the content of the core phase varies , however the common shortfall is on solo time and the 150 NM cross country qualifier. So in most cases the "gap" in training content needs to be filled before the PPL/SEP skills test can be conducted.
