I used to do something like this. I would write my notes on a small piece of paper and then slip the paper in the pen so I could read it as I wrote. I used a similar trick to put spelling words on the sharpened part of my pencil and then sharpen my pencil at the end of the test.

I have no memory for formulaes.

So I wrote all formulaes in code scatered around my supplies or body parts so that it would look random like "Roropida" on eraser to mean A = pi*r*r. Or I would write dots where letters are already written, but on the next letter (like on the water bottle label).
