The videos are intended mainly to help revise, but also to help catch up missed lessons, so they all end in what can be used as notes.

The level is indicated for each part of the topic, but this can only ever be in general terms.

The videos are not embedded, to speed up the page load speed and make it easier to navigate. Instead the links open a new page in YouTube (or similar).
