2391 theory pass rate

[GLENNSPARK]

GN3 and revise on formulas,procedures,etc,you may not get any questions to do with old papers but they can help with the way answers should be put down to maximise points on each question,lets hope that the 2391 stays and is never made multiple choice,hope you get through it.

formulas will most likely be of the PFC from voltage/impedence sort....or stuff round about that kind of thing....adiabatics would be unlikely....but you never know...lol..
