I mostly teach online but am happy to do lessons in a local library during exam season when students need more help.

The way I teach wavies based on the students needs. for example if someone tends to learn through audio - we can record lessons / while if someone is a visual learner - it will be better to teach them models by drawing diagrams. But mainly I use exam checklists.
I have exam checklists- these are simple lists which students are given when they start with me. They will choose topics they are unfamiliar with/ struggle with or have not yet covered in lessons at school - this way I am aware of what my students need to know.
After each lesson I tend to do a small pop quiz and give them 2 questions to practice and give me before the next lesson. this way I can mark them and provide feedback.
