Exam preparation was a key element of most lessons, as exams were after all the final "end game" for your O levels. One of the most important approaches was always to define the problem and your solution to it as clearly as possible, so that the marker would understand what your thinking was. Not only should you draw a diagram, but it should be big enough to be understood easily.
By exam time, any member of the class could be singled out and expected to answer the question "what do you do first" with the standard response "Draw a Dirty Big Diagram".
I've just put a comment on another of your posts but this one is more apt as I have specifically mentioned 'Draw a dirty big diagram'
