Exam Nerves

I’m so very, very nervous about tomorrow’s practical exam. I’ve just gone over the Physics A2 topics and there are a hell of a lot of equations in there. It’s also more complicated than the AS in terms of physical equipment, too. While I’d played around with resistors and LEDs at school, I’ve never plugged in a capacitor or examined magnetic fields using anything more complicated than iron filings. I just want the exam to be over.
