That created SEC. Maloney Act of 1938 created NASD. Indahook, you should be fine. Obviously, the amount of time is irrelevant. As long as you truly understand most of the material you'll do well. I took 24 in 1992, an passed witha 70 on 1st shot. I would imagine it's been made more difficult. Good luck, Indahook! (and congrats on the new job)
The 24 Is a stupid stupid test. 1 month should be more than enough, as long as you can remember and retain a lot of boring information. The deerborn book was good enough, however mine was outdated. The only interesting part in it was the capital requirements on being a market maker. Good luck and enjoy!
