As you may know, in previous years, mathomat and curve sketching sheets have been permitted for mathematics students. However, these are no longer permitted as of 2020.

In class, I often find myself using a mathomat to quickly sketch in triangles for visualising trig questions, using the sine curves to cheap out on sketches, and the circle stencils for drawing quick circles.

After hearing that this would no longer be an option, I decided to see what

*can*be used, and found out that for Advanced Mathematics, there's not a lot.

The official list on NESA's website shows:

- NESA approved Calculator
- Ruler

Now, the assumption could be made that the exam will be designed in a way that we will not need set squares or protractors or mathomat sheets. However, throughout my schooling career I have not known NESA to ever be kind or make something easier on us, so I'm not going to take that at face value.

Moving on to my actual question, being a design minded student I started to think "What can I do with my ruler?". Now, my dad told me about how his friends used to drill holes in their rulers and draw circles using one pen in one hole as a pivot, and the other as a pen.

But I wanted to know how far I could take this. I thought well, if the holes pass, can I cut out entire shapes into my ruler? Am I allowed to cut out my 45° triangle and my 30-60 triangle for quick drawing? Am I allowed to put a small stencil of circle types to draw in?

Then I jumped to the final stage: "What if I just 3D print my own ruler?". If I could get away with that, the flexibility was endless. Make the ruler a little bit taller than a typical ruler, to fit more shapes in the centre. Make one side of the ruler a precise sine curve.

I am struggling to find anything that outright says I

*cannot.*Honestly, I'm struggling to find any solid information on equipment at all.

Perhaps I'm the only one that sees it like this, and there's some unspoken rule that makes this obvious rule breaking. Or maybe I've overlooked some rule on modified equipment. If so, I do apologise for the lengthy question with a disappointing answer.

I've always been a bender of the rules. Before my trials I bought a specific brand of sharpener that was large and round with a flat base. I would wrap my watch around the sharpener, and place the watch-sharpener combo on my desk. The sharpener held the watch up, and I could angle it so that the time pointed straight at me, and wasn't perpendicular.
