For exams from 2008 onward, candidates are automatically provided the curriculum readings from the CFA Institute at the time of registration for the exam. The curriculum is not provided separately in the absence of exam registration. If the student fails an exam and is allowed to retest in the same year, the CFA Institute offers a slight rebate and will not send the curriculum again (the curriculum changes only on an annual basis).
