I have a very able A2 Physics student who I would, and indeed did, confidently predicted an A on the January module exam. She regularly achieved this on past papers under exam conditions before the exam. She got a U in the module. Just stupid mistakes and complete failure to do things that she could do with ease the week before. Final module coming up in a few weeks. Again, she is well on top of the material and can do all past paper questions. Any top tips to help ensure that she doesn't bomb out again?
