Just to confirm. Does writing down the exact notations in the formulas generally carry any points on the exam? Or is it fine to just use the inputs and show the process of calculation?
Writing down the formula proves you remember it, which gets you some points already. If you jump straight into the numbers and e.g. copy down the numbers erroneously, you lose all points because the examiner can’t see if you correctly knew which concept and formula to utilise.
