Series 7 vs Series 66
The Series 7 is FINRA's full securities representative license for executing trades. The Series 66 is NASAA's combined state law exam (Series 63 + 65 content) that requires the Series 7 first. Together, they give you complete flexibility to both trade securities AND give advice for fees.

Frequently Asked Questions
QCan I take the Series 66 before the Series 7?
No. The Series 66 requires the Series 7 as a prerequisite. You must have passed the Series 7 before you can register for the Series 66.
QIs Series 66 the same as taking Series 63 + 65 separately?
Effectively yes - the Series 66 combines the content of both exams (state agent law from 63 and investment adviser law from 65). It's more efficient for Series 7 holders because you take one exam instead of two.
QDo I need both Series 7 and Series 66?
If you want to work at a dual-registered firm (broker-dealer + RIA) and both execute trades AND charge advisory fees, yes. The Series 7 alone only allows trading at a broker-dealer. Adding Series 66 enables fee-based advisory services.
QWhat if I already have Series 7 + Series 63?
If you have Series 7 + 63 and want adviser registration, take the Series 65 (not Series 66). The Series 66 is only more efficient if you haven't taken the 63 yet. There's no need to retake 63 content.
