Also, remember some of actual formulas that are not on the first page, e.g. area of pyramid (e.g. 3D pytahgoras), density = m/v, speed = d/t and remember LSF, ASF, VSF when working out a side, area or volume of a shape.
Also when working out things like miles per hour, make sure that in your calculation you use the HOUR and not minutes or seconds. So 15 minutes would be 0.25 hours.
Also, knowing some key things like that there are 3600 seconds in an hour (crap example... but oh well) - or maybe formula for angle using Cosine rule (saves time as you don't have to rearrange it in the exam) can save you some time, at least a few seconds, as you don't have to work it out, just write it down.
What mark are you aiming for?
I messed up paper 1 and I'm aiming for 100 marks on this one to get A* (lol).
