Hi Aiden,

- I think the way that you have written x=5 in the advice is the way you should write it in the questions. I think that would make it a little clearer. At first, it looks like x=5 is a continuation of the expression. I think this is probably better:

'At x=5,

what is the value of 4x^2+x+53?'

- You need to say in part c) that the user is to use pi=3.142. You did it for part e) but not for part c). I did the question using my calculator pi button as you hadn't specified using any simplification, and the answer I gave was marked incorrect due to different rounding. I then had to use the same answer when finding the volume of the cone and it accepted my answer that time, when multiplied with h/3 so it is only a problem for part c).

- You have the radius, 'r' written in LaTex in part c), but not in part d).

- In part e), "Geraldine has a ball of radius 31.4cm // she wants to find the volume of the ball." doesn't make sense. You're missing a full stop and a capitalisation, or an and. Also, I think the next sentence should be on a separate line personally.

- I don't know if it is automatic, or whether you can change it, but your rounding requirements in part c) and d) are specifying 1 decimal place - singular, but saying "Round your answer to 1 decimal places" - plural.

Hi Stanislav,

I think for part c) and d) you could rearrange the format for inputting answers into an actual fraction with gap fills included. Then it will match the form of the question when it is asked and might make it easier to understand. I have included this in some of my questions so if you are not sure how to do this, I can show you.
