Thanks for the review! c0b38b8 fixed the layout problem.

Thanks for the ping. We can remove sections for both Tutorials and Lesson Plans.

I have a feeling we'd want to update the text and videos on this page entirely, but we can open a new issue for that later.

Checked all the links and layout looks good now. Just need to update the title tag and we can probably merge. If we need to remove sections we can follow up. I have pinged for input though.
