I teach SL and HL at the same time. It’s always a hard decision to make but this year I began the first semester with Option H Further Human Physiology with HL. Not an ideal start, but I keep in mind that they will have the October break to revise and complete more Paper 3 questions and also during their summer break I will give them a nice packet of Paper 3 questions.
It shows my HL students that they will have to work hard right away if they expect to pass the class.
If you have a better suggestion on the subject, please do let me know.
