Especially noticable with YL teachers, this might prove to be difficult in terms of grouping the material.

Grouping material

Large schools make so-called “Calendar plans” for specific courses. These usually include dates, material that needs to be covered. The more conscientious could even provide planning or resources.

However, if you work in a small one or without particular guidance, this piece of work might fall to your responsibility

It might be unreasonable to plan ahead for a year, but a short plan like this one  planning-ahead would provide you with quick source of information on where you are, what you need to do next and how not to run out of material in the middle of the year.
