--- End quote ---
the precision is the least value that can be measured. Example: for these values 12.0,12.5,13.0 the precision is 0.5
but in our case 14.2 14.7 15.1 the precision is 0.1 ;D

O ok, but the question asked something different. O well.

Question 4,
the one with the potential difference across the diode,
the mark scheme seems to have a mistake, because it misses out question 3b)
The answer to question 4 needs to be A
It can't be D because the diode is reverse biased.

I knew it! I wrote down A as well. It just had to be!
