Is my school allowed to do this?

Yes they are, but it's a pretty *****y thing to do. Is there a reason why they're doing a paper from the 90s?

I have my mock exams coming up for the sciences and my school said that they're going to use papers from the 90's. The specification back then was much different and I'm pretty sure the mark scheme was too, so there's no way I would even be able to revise off of past papers to familiarise myself with what the examiner wants since papers from back then aren't even accessible to students.

The grades we get from these mocks will be used to predict our A2 grades which will obviously be used for our university applications. I'm a bit worried and I'm not sure if this is allowed, the teachers at my school can be somewhat irrational so if I tried bringing up the problem to them they'll most likely end up making an excuse.

Any advice?

Unfortunately they can pretty much do what they want- for a prelim once, my physics teacher actually used questions from a paper he had sat for his higher exam. Its worth mentioning that he is not exactly just out of university, and the questions were from an exam paper published before some of the class were born!

That's a shame, I just think it's really unfair because firstly they were too cheap to enter us for real exams and now they're giving us these papers. Why not stick to the 2016 AS paper, I have no clue. *sigh*

I'm pretty sure they can't do this. And anways can't they just create a science paper, by putting a mixture of pass papers in one paper or come up with questions them selves

My school were too cheap to enter the AS exams as well i found it rather silly, cause now teachers will know whose still on the course and who isnt before we've even got our results (my schools making us wait till results day.. ) I wish you luck!!
