Hi i want to ask if examiner asks for six substantive procedures and i give 7 then if one of my procedures is incorrect will my one extra point compensate for that? Will i still get full marks if my other six procedures are correct?
There is no negative marking, so your incorrect one should not count against you.
Beware of giving more examples than the examiner wants: the extras take time to write out, and you will never be given credit for more than what was asked for.
