For the first session I usually start with a bit of a quiz, a list of questions that pupils typically struggle on.
It's mostly for me to understand areas where the pupil is strong at, and areas where we need perhaps a bit more work on.
Then the format is usually 15 mins of recap from last session followed by 35 mins of new topic/skills. And then lastly finishing off with 5/10mins of the pupil discussion where the pupil discuss the next sessions topics/ areas they want to do more of etc.
