The OPBS examination is a multiple choice question (MCQ) based examination conducted with two examination papers. Each paper consists of 100 multiple choice Type X questions (an introductory statement and five true/false responses).
The two examination papers are conducted over consecutive days. The duration of each paper is two and half hours.
Type X question example
These questions consist of a stem and four distractors. A candidate needs to answer whether each distractor is true or false.
A correct answer to each distractor is worth one mark. Each type X question, as a whole, is therefore worth up to four marks.
The facial nerve:
A. contains taste fibres from the anterior two-thirds of the tongue
B. arises from the pontomedullary junction medial to the vestibulo-cochlear nerve
C. has a sensory root which is larger than the motor root
D. supplies the buccinator muscle
D is true and A, B, C are false. The facial nerve contains taste fibres from the anterior two thirds of the tongue, is medial to the vestibulo-cochlear nerve and has a sensory root lateral to the motor root.
