This is it.  The final module.  We made it!

I'm bringing back our old friend for a final lesson - the Universal Table!  We'll see how it helps us with ratio questions, which can often cause confusion once you get past the basics.

We've got a little more quadratic algebra to get through, and some lessons on the laws of indices.   We take a good look at Venn Diagrams - but if you're sitting the WJEC paper in Summer 2022 you can skip these lessons (as they have been removed from the syllabus for this year only).  We'll also get stuck into some more "hidden problems" along the way.

Last push.  Let's do it.
