['My husband recently spent a year studying for the different parts of the CPA exam.', 'What is the CPA exam?', 'Certified Public Accountant - he passed all 4 exams with flying colors!']
I bet he must be extremely relieved and happy to have that exam behind him. Those exams can be extremely nerve wracking. Did he have longs periods of study time?
