If you have ever been a student, then the ritual will be familiar to you; cram an entire semester’s worth of information into your brain over the course of one day (or one night if you’re a real go-getter)), in order to spill it out on a piece of paper on test day, and the  never think about the information again. Because honestly, you couldn’t possibly be expected to remember all of that. It is certainly not the most effective way of long-term learning, but we sure rely on it.
