1) The CFA exam has nothing to do with real world work experience or education. That is in order to pass the CFA exam, you need to enter the “CFA make-believe” world where real life experience does not apply.
2) Those who have real world work, where the average entry level job requires 60+ hours of work, have less time to study.
I always advise CFA candidates to be prepared to memorize laundry lists of things that have nothing to do with what you learned on the job. Also I suggest to be prepared to modify your education to fit the CFA view of the world. That is the key to passing.
