Feeling overwhelmed by securities licensing exams? You’re not alone.
With so many Series options, it can be tough to decide which one aligns with your career goals—especially when comparing the Series 66 vs Series 63. These exams may seem similar, but they serve very different purposes. One opens the door to dual roles as an investment adviser and securities agent, while the other focuses solely on state-level compliance for securities transactions.
So, which one should you take?
In this article, I’ll break down the key differences, what each license qualifies you to do, and how to choose the exam that’s perfect for your career aspirations.
Key Takeaways
