Argh, by the looks of things I'll get about 60 this time; do you think this could be enough for a gold this year? Also, has anyone got the answers/solutions to q.21, 23 and 25?

The paper says "the fourth is the units digit of the sum of the second and third digits", so it can only be 1 digit.

How do you prepare for these papers ?
Having just checked over my answers, I'm certain I got only got 45(bronze) ,but after going through a past paper prior a day before the challenge and getting up to around Q22, I'm curious as to what I'm doing wrong in terms of my approach and how quickly I should aim to complete the questions.
