Sounds to me like your memory works fine... just slower than you would like.
Have you used the memory supercharger tape that came with the course? It really pays to use that tape nightly for at least 1 week.
The other option is to draw mindmaps even though you know the stuff... the trick in remembering something is to store it in the mind practice exaggerating the images in your mind in a number of ways... imagine feeling, tasting touching, smelling, hearing stories and picturing... make them funny. There are lots of techniques.. finding the one right for you might take a bit of exploring.
A starting point would be to acknowledge that you have an excellent memory... if delayed
