Query on computer element of Unit 31 skills test

Please excuse me if this is a stupid question but I have limited experience with computers for business -so is it easy and straightforward to access a spreadsheet and the (SUM?)formulae for calculating moving averages etc on the centre supplied computer to be used in the exam, i.e would it be the same as my own (which has excel)or would you need to be familiar with the computer in question's set up?

as long as your familar with excel you have no worries
