Ds1 (Y9) is going to start GCSE History next year. He has the year 9 exams next week and they are used to set for GCSE, so he wants to do well.
Before Easter, the teacher gave the class a revision list for the exams. It was six broad topics that they've covered this year. DS1 made a revision timetable and worked his way through all the History stuff during the holidays. However, yesterday, the teacher gave the class a different revision list. Now there are three topics, all of them in the original list, but requiring much more depth.
I don't think its great that the History dept have done this (without even acknowledging the change), but is something to be concerned about? Ds1 can cope with it because he's on top of all his revision (for once), but it wouldn't be good if they were disorganised like this over the next two years.
