If they ask us for the voltage gain should we put a sign?

I dont think its required but im fairly confident you wouldn't get penalised if you did. Read through the examiners report i think its mentioned in there.

"The voltage gain was the magnitude of the gradient of the linear section of the graph, which was 300"  this is from VCAA 2009.

if the gain is 300 with a negative gradient.

i usually put (-)300

Same, unless it is asking for the magnitude - be careful! :D

According the VCAA the voltage gain is just the magnitude .

True, but I like the put in the negative sign anyway, unless a question following it asks for whether it is inverting/non-inverting.
