I have had plenty of students who scored Cs in prelims but As in
O Level.
Conversely, I have also seen students who score As in prelims
but Cs in the national exams, both O and A Levels.
Nothing is absolute till the results are received.
My school is like those who get A for prelim is cfm A in o
level,while those who get B for all subjects usually o levels also
hit jackpot and get a lot of As also
Hope to see my A maths jump from an F9 to an A2 though =/
