Overall, I found it ok, probably similar in difficulty to last year, probably easier than 2015. By far the most difficult thing was time pressure. I didn't manage to start the second half of one of the question and the last two parts of another (I just had to sacrifice them). I found the multiple choice easier than last year, with one tricky question I ended up having to semi-guess because the time was up. I was dissatisfied with how I answered Q5 because I got it all right, but I was so pressed for time I was a bit sloppy with my explanation, ie I explained things very briefly before working out the actual answers. I'm guessing around 75-80 based on what I didn't get to finish. Could be lower if I find I made silly mistakes once discussion is allowed
