There’s decent science on why this isn’t possible. Basically you need to space things out to give the brain time to work out what to put into long term memory
Approving coursework doesn't mean that the concepts sunk in. It just means you have new tools to further your understanding of everything, but it still takes a long time for it to sink in. During that time maybe you just need to do nothing, just let it sink in, but in my experience everyone ends up needing some time.
