Talk to Neuro Physician on Neurological

Anonymous plz.. my daughter was extremely bright student always a position holder but from past 2 years she herself is worried .she studies she gives exams and probably write wrong answers in exams .. she says ive written correct and I'm confident but her result is usually failing in subjects...not just one subject but a decline in many subjects..she is very worried so am I that what actually has happened to her.. the teachers are saying that she is a bright student and not a slow learner but there is something terribly wrong resulting in her drastic decline..even now she failed in 3 subjects and she is claiming that this can't be as she wrote the correct answers..do u think is she suffering from any neurological problem?
