I usually start with a review of previous day lessons about a particular subject.
Then I share with student the lesson objectives of the current topic.
Afterwards I try to bring either myself to at student level or vice versa.
Thereafter, I start describing the meaning, brief history and root of the topic.
And at the last I go on discussing with the student all the key cases and material. Along side doing so I share sample answers and past papers solutions to help my students to come up on my pace.
