What the treatment is, and why it is not in this course
There is real treatment for this and it works. Broadly it involves working with a trained person on the appraisal and on what your attention is doing in the room, and for some people it involves carefully planned practice under conditions you both agree, at a pace you set together.
We are not going to walk you through the second part, and you should not build it for yourself out of an article. Sitting yourself down in staged exam conditions to get used to the fear is exposure work, it goes wrong when it is done alone, and people commonly push far too hard, frighten themselves badly, and conclude they are beyond help.
That is also why the plan in lesson five was framed as a memory technique. Writing down what you can remember is a way of finding out what you know. It is not a mock exam and it should not be turned into one.
