Yes, I agree with this, before you take it you have to carefully consider. If you want to learn more, and all by yourself, that's really a good instruction. It could supervised you.
Concerning finding job, so far as I know, most people consider to take CFA, FRM or Actuaries already hold a work position. That means comopete with their colleagues!!!I I am now organising the FRM Review Session in UK, I never met the graduate students enquiry this, also we send a campaign to all graduate students in CASS Business School, City University(Although can not compete with OX or Cantab, it has strong relationship with London City). no reply at all!!!! I think this is a good example to explain it.
How expensive the exam is, all by yourself?????
If you get a job offer, the company may pay for you for your professional education!!!!! That's ture!!!!
