Using Solution Videos
When you do get a question wrong, a solution video will be made available right then and there. The video will show you how to solve that particular questions and the underlying concept of that question. While watching the video, it is much more important to latch onto transferrable concepts than to specific variables or words used in that particular question.
Example: if the question involves a function defined by f(x) = x + 5, it's more pertinent to pay attention to general facts about function problems than to specific details-- like the variable x and the number 5 that happen to appear in this particular functions question.
