#5: If units are used correctly, units substituted also CANCEL OUT in rearranging.

I love this, taught it properly at uni as an actual part of the method, but so handy for checking calculations! ;D

So I made a HUGE mistake in my Physics trial by forgetting to take my calculator into the exam room with me and I didn't realise until the exam had actually started. I still did all the maths questions, but I only had formulas and substitutions and not an actual answer.
Most maths questions were 3 markers, would I still get at least 1 or 2 marks out of them?

Yes. If you can demonstrate that you can use the correct formula with correct substitutions, you get a part of the marks available.

Damn! What a bummer, good on you for still making sure to maximise your efforts in the room! If it was a 3 marker, you should get two marks out of the three, as long as you showed all your working. If the only line missing was the solution itself, you'll get 2 marks! ;D
