This is some bad advice. While there is some "irrelevant" ATPL theory content, a lot of it is very much relevant.
OP, as a University student you probably understand that revising throughout the year is a lot more effective than cramming it all during the week or two prior to the exam. This is at least my experience. I recommend you go over a few of the topics others have pointed out. If you have a genuine interest and motivation to learn, then of course you'll remember what you have studied. You'll thank yourself further down the road when you're preparing for exams.
