Physics OCR A2 Pratical

It certainly is.
Any teacher who helps students in an exam or breaks exam security would face disciplinary action at the least and could lose their teacher registration so they'd never work in teaching again , at the most. And yes, teachers do this and get caught every year. The pressure to get good results makes folk do crazy things.

if you look at the question it asked to take ln of (V/mV) or something along those lines....thats because the voltage (i.e the value of V) has the value and an associated unit namely mV so the mV's cancel and you're left with a pure number.

e.g. if you found your voltage as 200 mV (say) you can't do ln 200mV..so you do ln (200mV/mV) i.e. ln 200

Well i thought that if you were given help in the practical then the teacher had to make a note of it and write it on the back of your paper, from this, OCR decides how many marks are deducted
