Well, FJ came back from school today...good news is everything settled, though not exactly to her satisfaction. The teachers came to a consensus that so long as the students answered with the key words from the textbook, the answers is acceptable, so now they have to mark all the answer papers again. As for FJ, she only got 1 extra mark, since she answered in her own words, and did not include the key words from the textbook.
Was the effort worth it? I suppose so... but then the jury is out. Probably by going all the way to the Asst. Headmaster, FJ has most likely antagonise the teacher concerned. All I can hope is that FJ will not get this teacher in her class next year. Otherwise, FJ will be picked on or maybe just ignored! But then, looking back, all this would have been avoided, if the teacher concerned had kept an open mind and listened and explained to FJ instead of telling her to go away and challenging her to see the Asst. Headmaster, which I strongly feel is intimidation as she was most likely thinking that FJ would not have wanted to approach the Asst. Headmaster!
