“There are so many students who although they have studied all of the material will not go and take the exam because they fear failure! … if they humbly say,” Bless me that I may do well because I cannot do it on my own; but with your blessing I will try…” then with humility they will receive both the Grace of God and divine enlightenment. Later as they begin to take their exams they can also pray to their patron saint who will also help –depending on the faith and devotion they have.”
(Elder St Paisios of Mt Athos,  ‘Family Life’)
