When answering a question, if you use a valid (and potentially more accurate) method of calculating an answer but isn't listed in the mark scheme, would the examiner always definitely give you full marks for the question?
I ask because in the June 2012 paper, there is a question giving a graph of magnetic flux against time. It then asks to calculate the peak e.m.f. induced. I instinctively just worked out an equation for flux and differentiated it with respect to time, and maximised the trig. function involved. This gave an answer within the the range of the correct answers listed but the method used isn't listed. They wanted you to find the gradient by drawing a tangent. Would I still get the marks?
NOTE: It was a 3 mark question.

yes - the examiners get a more detailed sheet than the released mark scheme giving details odf what is accepted and what isnt.
Differentiation methods were accepted.
