For Q 15,this was indeed tricky.a\As the readings were only taken every ten degrees, the rate could then reach the maximum between the measurements. This could mean between 30°C and 40°C or between 40°C and 50°C for this data.

2004 not 2002 ,btw i started doing them in february so i thought i will have enough time and practice,(the more the better) but honestly 2004-2009 ones are easy af like i get 39 or 40 in them,but recent years i get maximum 36..Are 36/40 (i messed up in my p3)
I almost got a heart attack when you said from 2002 to 2018 lol.Instead of doing 2002 papers you should have just done
2012-2018 papers all varients like me :p
