Hi all. Mature student, Year 1 Undergrad. STEM subject, if it matters.
The ROGO system has got me baffled 
I’ve just sat a mock. 32/66 correct. My % score was 6%. Because they knock 29 off to adjust for potential “guessing”.
I’m probably being dim, but how many out of 66 do I have to get to get a pass of 40%? When there’s 29% being knocked off 
Sorry for what is probably a very stupid question but being examined this way is really stressing me out.
