We have those dot things for our GCSE science exams but they dont seem to fail.
Really?
What exam board is your Science Exam with?
Never heard of an optional choice GCSE Science Test.
Mines comprised of Modules and Coursework.
Teachers hate marking all the coursework.
I've only ever used a dot-mark test when doing some SATs papers and then in the Annual UKMT test.
United Kingdom Mathematics Trust.
They send out tests to schools once a year to find people who are really good at Maths. Who then go to a very boring Maths competition or something.
