It's so interesting to me that interleaved practice is an effective learning technique, that's probably the single method of study I used consistently throughout my entire schooling. Slightly bored of one subject? Okay switch to the next. Bored of this one? Switch to the next. CONSTANT context switching. I thought I was "cheating the system" by making my homework more interesting, who knew I was learning more effectively by employing a (moderately) effective study habit!
