Today I finished uploading PDF solutions to display below each video. A student and a tutor both suggested that it would be convenient to have the option to quickly scan the written solution before watching the video since sometimes only a little help is needed, and the written solution might be enough. Since I still had the written content in Microsoft OneNote, it was fairly straightforward to render each solution as a PDF. The content is the same as in the video, and it's a bit messy since it's a snapshot of after the recording was done. I hope it helps!
