My brother graduated from university last year; he will soon …

Analyze the question: The sentence says your brother graduated from university last year and "will soon __". In Nigerian universities, what happens after graduation? There is a convocation ceremony where degrees are formally awarded. So we need the verb that fits that idea.

Explain the concepts:

• Matriculate means to be formally admitted into a university (matriculation ceremony). It happens at the start of a course, so it does not fit someone who has already graduated.
• Convoke means to call people together for a meeting or assembly (e.g., "The Senate was convoked"). It is a transitive verb that needs an object, so it does not fit here.
• Convocate and convoce are not standard English words in this sense. "Convoce" does not exist.
• The word the examiner intends is the one related to convocation (the graduation ceremony), i.e., "convocate", used in Nigerian English to mean "attend or take part in one's convocation."

Working through the options:

• A. convocate: relates to convocation, which comes after graduation. It is the only option that matches the context, and it is the one the examiner expects.
• B. convoke: means to summon others, so it does not make sense with "he will soon..."
• C. convoce: not a word.
• D. matriculate: happens at the beginning of studies, so it contradicts "graduated last year."

A note on accuracy: "Convocate" is not widely recognized in standard British or American dictionaries. It is a Nigerian English usage. For JAMB, go with A.

Answer: A. convocate

Exam tip: Link the ceremony to the stage of study:

• Matriculation = Matching in (entering the university)
• Convocation = Completion (finishing and receiving your degree)

When a question mentions someone who has already graduated, eliminate "matriculate" immediately.
