Non-written exams are probably the most nerve-wracking type of exam out of all of them because there is a level of performance required for this type of exam and you (unfortunately) will not necessarily be given enough time to consider your answer or your course of action. There are actually two types of non-written exams that are used most often: the first is the oral exam and the second is the practical exam.
The oral exam, to be specific, is where you are asked just one question pertaining to a topic taken up in the subject, and you are made to answer (verbally) as clearly as you can withing a given time limit. Should your answer be unclear, you will be asked by the proctor a related question for the purpose of clarification. It is, in certain circumstances, not difficult to pass this exam because talking things out tends to help with memory and analysis.
The practical exam tends to be less cerebral, and sometimes are pretty physical. Practical exams include the performance of memorized speeches, musical pieces or dances; all in all, practical exams expect you to prove that you are capable of applying theory and practice into real life situations. Practical exams are actually a higher form of proficiency exams, and as such, they are based on skill and not pure theory.
The best way to handle non-written exams is to practice, practice, practice. It's a well-known fact that it is the nerves that affect your performance in these situations. The more practice you have, the less nervous you will be.
