Do we need to include auto-checks / reasonableness checks under "Methodology" for Paper 2 summary? Also, for sheets that have been created for Paper 2, does that mean we are not supposed to make any changes to them? i.e. include checks? Thanks.
Firstly, as a rule, these sort of questions can be answered by looking at the examiner's report - there's a fully detailed marking schedule which will give you a very good idea of what is required just by looking at what you get marks for. But to answer the questions - no, you don't need to change anything in the model apart from the extra calculations that are required. You can if you want, but you'll get no credit for it, so it's a waste of time. Similarly, there are no marks in the schedule for auto checks of the type you'd normally use in paper 1. However, there are loads of marks for explaining results, which is similar in concept to what reasonableness checks are in Paper 1 - namely, a way of showing that you understand what's happening, and that it make sense.
