I know it's a video for teaching so slower is expected to help make clear but you cant spend 15 minutes on a question like this

@@ALevelMathsRevision I would just say being a bit quicker is more helpful more being exam ready, loads of students run out of time in further maths and it was quite a slow method but it was a clear good video

[@ALevelMathsRevision]

but the purpose of the video is to show how much better the substitution method is than the alpha beta gamma method. The method only lasts 6 mins so I think we agree speed is key. The remainder of the video was showing how inferior the alpha beta gamma was. So I think we agree :-)

@@ALevelMathsRevision yeh I'd say we do overall

[@kylezinho_]

he hasn't spent 15 minutes on the question, he's shown two methods.
