‘By numbered in increasing difficulty what I meant was they seem to do 3 papers in each of the 3 sciences – so for Physics P1 first which is easier than P2 next which in turn is easier than P3’
P1, P2, P3 (likewise in chemistry and biology) should all be of a reasonably similar standard. This can lead to problems with early entrants who may sit P1, B1 or C1 earlier than normal- and thus meet the rigour of GCSE when they have not been fully readied for it.
‘I assume from what you said you can’t mix higher and foundation papers in the same subject during the same year – so she will do all foundation papers P1 P2 and P3 in Physics – there would be no point as you can only achieve a C grade as soon as you sit one foundation paper in a particular subject? ‘
A candidate can sit any paper at whatever tier they wish to do so, at any time. A candidate can change the tier that they sit the paper at immediately prior to the exam. Parental confirmation should be required.
A mix of successful higher and foundation results can indeed lead to a B grade. Thus my son managed to achieve a B grade in Welsh despite sitting the foundation paper. His coursework raised his grade.
