Yes, of course. They can deal with it to a great extent. In any test situation, a whole range of unpleasant emotions such as fear or anxiety can occur, which can reduce your quality of response or completely block you and make it impossible for you to show what you have learned. You can engage in conversation with other colleagues just to divert thoughts from the exam itself, to briefly leave the "topic" of the exam itself. "Only be brave, only be positive, you can do it, keep repeating it to yourself and believe in it deeply."
Feel free to send, I'm glad it will be useful. I wrote my book on this topic
