The question tested candidates’ knowledge on computer hardware and CorelDraw.

It was reported that majority of the candidates demonstrated fair knowledge of computer hardware. However, a good number of the candidates mixed-up system unit of a computer with the central processing unit of a computer. Candidates also showed poor knowledge of CorelDraw.
