Common Study Mistakes (and What to Do Instead)

Many people slip up while studying. Here are a few common ones I see candidates make the most mistakes in to avoid (and what to do instead).

❌ Just skimming practice exams without reviewing your mistakes
→Do This Instead: Take mock exams and dig into every question you miss. Understanding the why behind each answer is what actually builds retention.

❌ Sticking to one study method
→ Mix It Up: Flashcards, outlines, practice questions, and timed quizzes using different formats help your brain lock in the info from multiple angles.

❌ Not Having a Clear Study Timeline
→ Plan Ahead: Going in without a structured study schedule makes it easy to fall behind. Create a roadmap like an 8-12-week plan to review weak spots, and leave time for full-length mock exams.

❌ Neglecting Key Content Areas Like Economic Factors and Investment Vehicles
→ Revisit Them Often: These topics show up across multiple question types; knowing them cold gives you an edge.

💡 Pro tip: When you learn a rule, explain it as if you’re talking to a client. If you can clearly explain it to someone out loud, you understand it deeply enough for the Series 66.

Do You Need the Series 7 for the Series 66?

If you’re researching the Series 66, you’ll definitely hear about the Series 7, too, and for good reason.

• Series 7: Covers product sales
• Series 66: Covers advisory knowledge and fiduciary standards

Both the Series 7 and 66 form the foundation of a well-rounded, fully licensed financial advisor.
