Hi Everyone, new to Mumsnet so hope I'm doing this right. Would appreciate advice re my DS who is 18, y13 in 6th form of academic state school. Did ok at GCSE, not fab grades but put that down to not enough work. But real problem has been AS/A2 levels, terrible grades (Cs Es Us). This despite good school reports and no prediction of such by any teacher in any subject. He is intelligent, articulate, sporty, and an all-round beautiful human being (goodness I know this is sounding like a delusional mother), but on his classroom performance, his written exam results in no way correlate with his abilities. Am thinking there is some undiagnosed prob, have booked app with Ed psy as starting point(?)as his exam failures are really getting him down. We know his intelligence is not in doubt, his younger sister is applying to Oxbridge and she's no cleverer but does well in exams. At a loss as to where from here. Need to help but just don't know what needs to be done, help please.
