At the end of the day, they can only test what's in the syllabus. Just read up on safety, experimental method, validity/reliability, do heaps of practice and you'll be fine. Just treat it as any other test.Does anyone else hate science practical exams or know any tips to prepare for them?
I hate the idea of a test being out of your control but I know a few people that love them because they don't need to study as much.
