A lady having a problem of learning, self confident lose and has a slurring speech while given viva's.and she's a medical student.what to do to get off?

Viva's?: Have no idea what this is. The individual with problems learning and loss of self-confidence is obviously exceedingly intelligent if she is in medical school. Almost all med schools have programs for students with problems of this nature. If not, have her see a competent clinical psychologist and get to the root cause of these problems. It will help her enormously in future life in many ways.
