Hi, I am wondering how to teach mixed HL and SL classes with DP Biology. The timetable has 7 lessons per 2-week cycle. HL students go to all 7 and SL students go to 5. Bearing in mind the SL content is required to do the more in-depth HL content I don't see how I can structure this. At some point, at the beginning of the first cycle of the year, I am going to have to teach HL content. Any advice would be greatly appreciated. Thank you!
