No its not reliable. if you read the first post on Page 3 of this forum, they got the radial survey question wrong as well. I'll post up the exam page online now.

The teacher who marked it on the MCQ gave Q14 D (was deemed wrong), Q15 D (was deemed correct)


Im skeptical because when I did Q 14 :







Which was marked wrong.

In that case, yeah, answer should surely be +/- 0.25%.

Yeah it appears that these markings are quite unreliable.

Is the reason the teachers marked that wrong that they didn't understand the theory themselves?

If you have access to other years' papers from that school, you could maybe check how correctly those ones were marked, to see if this is a recurring problem.

Just wondering if there has been a mistake made in the Year 11 Oxford General Maths textbook for Chapter 2 Q 11.

Saw an example of this nature from the text book:










My initial thinking with this question was to find the Limit of Reading value which in this case, I thought it was 1 gram. (As I speak I've realised they have used the Limit of Reading value of 10 grams as stated in the question)





After having a deeper thought about it, I think the answer is (but I really don't like the logic behind it):
