GUINNESS NIG-GRADUATE TRAINEE
TEST TEMPLATE

For those preparing for the Guinness test;

The test is organised by WAEC.

The test format is as follows;

a) Verbal mostly GRE kind of questions
b) Maths mostly word problems
c) Logic problems
d) Management Problems for your discipline.

Out of the four segments, I found Logic Problems the greatest time ‘waster’ and difficult.
