In an attempt to continue producing increasingly sophisticated \(\TeX\) I produced some Mathematics booklets for Year 7's and 8's that mimicked the Cambridge ICE-EM NSW Mathematics series.
In essence, I was fleshing out entire textbooks into interactive booklets with space to write. As a result I learned to effectively produce figures and leverage the exam class.
I also learned how to produce far larger documents, with some booklets nearing 50 pages in length to satisfy 3 hours of tuition.
