Painful hand and shoulder

This morning I did the 2013 Level III AM paper in a timed situation to see if I would be able to write so much and how long it took me to answer each question. Oof, now my hand hurts dreadfully and my shoulder is sore too! Also, it got quite cold in Edinburgh in the last few days and I’d switched off the heating two weeks ago, so my feet were freezing! I had to turn the heating back on. I haven’t checked my answers yet, but I had to really scramble for time and could not answer one whole question.
I was thinking of doing a multiple choice test this afternoon, let’s see. One thing I learnt is that I should write fewer words for each answer — that would be beneficial for both time management and saving my physical strength.
