I find myself in agreement with you and hold up my hands to say that the scenario you describe is exactly the reason I went to a training school.
Some of the partial modules undertaken were actually meaningless.
A good description was that it is like doing a jigsaw without a box lid, no edges and some of the pieces missing!!!!!!!!!!!!!!!!!!!!!!
Just random pieces of information to be regurgitated for an exam.
A pointless exercise involving no understanding of the subject.
87% what a star!!!!!!
