will consist of forty multiple-choice objective questions all of which are to beanswered in 1 hour for 40 marks. The paper will consist of two sections, SectionsA and B as follows:

Section A:

will consist of thirty questions drawn from the general principles,techniques and uses of plane and solid geometry.

Section B:

will consist of ten questions in each of two alternative parts: Part I(Building Drawing) and Part II (Mechanical Drawing). Candidates will berequired to answer questions in one part only.

PAPER 2:

will consist of five essay questions on plane, solid and vector geometry.Candidates will be required to answer any three of the questions in1¾ hours for60 marks.

PAPER 3:

will consist of two sections, Sections A and B to be taken in 2¾ hours for 100marks.

Section A:
