You can get into interesting questions like "what is the stalling speed of a tiger moth at the top of a +1G loop?". Personally it was the continual posing and discussing of questions like this by my instructor (when I was 18 and doing the full-time Flying Scholarship that led to my PPL) that allowed me to actually understand the concepts rather than just parroting the answers from a standard text. Once I had a decent grasp my instructor would then finish off the topic with a "and if you are asked that question by an examiner the stock answer they want is '...'. "
In this way he both educated me and trained me to pass the test (which are often not the same thing!). Another point which is often not appreciated is that stalling speed is not only reduced in a climb (where part of the weight is carried by the vertical component of thrust), but also in a dive (where part of the weight is carried by the vertical component of drag)...
