Hey, i'm a new member, just signed up.

Anyway i've got an AQA Physics ISA on refraction tommorow, its the practical. The paper is next week some time as well. So far i've revised the basics like errors, uncertainty, percentage uncertainty and some basics on refraction itself.

If anyone can share any advice which will help me it would be appreciated. Thanks!

I messed up on my other ISA and have been given another opportunity to do an ISA on Optics. Would love hints on how to do well in regards to the optics ISA.

what's the precision of a protractor, half a degree or 1 degree? Also are there separate UMS for the two ISAs and you get your best one or is it your best raw score?

it doesnt matter in physics, it can be either (+/-) 0.5 or (+/-) 1.0
in chemistry they want +/- 0.5.
