We haven't learned anything, we've just been get sheets from a teacher who was absent for a whole term and then rushes the unit (2 powerpoints in one lesson, and worksheets for homework). She tells us to go to skl early on the day of the exam, then shows up 50mins late on the phone, and acts like nthings wrong, "dont stress guys"
If this was an exam that's being sat through an official examination body (University Examination, SQA, AQA etc), then I'd be inclined to say you have grounds for appeal. You shouldn't be kept that long waiting before an exam, might be worth speaking to whoever is your personal tutor/head of guidance to establish what can and can't be done.
Two PowerPoints in one lesson and worksheets for homework doesn't sound massively strenuous or unusual, if I'm honest, but again it depends on what level of education this is at. As for the number of worksheets in class, you have to tread carefully questioning teaching methods or academic judgement. That being said, if you *genuinely* feel you (and/or your class) were at a disadvantage, again I'd contact whomever it is that looks after your interests at your school/college/uni to see if you can raise a concern. They might question why you didn't raise it at the time, rather than retrospectively, so be prepared for that.
Hope you get it sorted, sure you will.
