I think Basic Unit Controls should go in Beginning or Intermediate.
Why are Unit Types in Advanced? Shouldn`t they also be in Beginning?
There should be a mention of Timing Pushes under Invasion. A Timing Push would be something as if your opponent is Zerg, and you know Zerg can get Brood Lords as early as X amount of time. So you time your push right before those units come into play.
Another common mistake (to add to Common Mistakes page) is people not practicing a build order. The first five minutes of a game can be critical and there are not too many variables of difference. Ironing out your build orders with precision speeds you into mid game faster. People who don`t iron out their build order are people forever stuck in Bronze.
