Which papers you already passed in fundamentals?
It depends that which F papers are left for you to attempt, your learning style and your inclination either towards the narrative or calculable paper.
Well you need to be more specific to your query.
If all other Fundamental level exams are remaining i would suggest you to use a mixed approch to attempt the exam that would be one practical exam and other narrative (Theory) Exam.
Unless you have a stong hold in only one of the above exam patterns then i would recommend you to choose likewise to get a head start in the Exams.
