Quote from gymratnyc:
I've heard of some people using Adderall to study for the CFA exam. I heard it helps you to concentrate, which isn't bad if you're studying for the exam
Well, it worked for me on the Series 7, 66, and CFA Level I.
As stated earlier, I failed Level II, and was using 10mg Ritalin to study, as well as on test day.
Anyone who passes II, and III is smarter (book smarter) than me.
