This might be as simple as the fact that you&#x27;re spacing your learning out less. In college you learned things over a span of 15 weeks, giving you many opportunities for spaced repetition, which is one of the most effective methods to make material stick. Now I&#x27;m assuming you learn material in much less time than a semester, so there&#x27;s less repetition and therefore less long term retention.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Spaced_repetition" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Spaced_repetition</a>
