Mindset

Passing with a grade A is achievable with a combination of four things:

a. organisation - of study, information, time and revision
b. information i.e. the syllabus - which has to be applied
c. exam technique
d. a desire to succeed and get the highest possible mark. Not just a 'grade sufficient for university' but the highest possible mark . You must have motivation

This is what was achieved in four hours - if you have longer, think what can be achieved!
