Introduction

If you want your financial license, you’ve probably wondered about Series 63 vs 66. Choosing the right exam now can save months of study and help launch your career faster. And choosing the wrong exam can cost you time, money, and future career opportunities.

Some people pick too fast without knowing the differences. Others pick the easier exam and later regret it when they cannot give advice or work in other roles.

Let’s start with the quick answer:

If you want to sell securities only, Series 63 is usually enough.

If you want to sell products and advise clients, Series 66 is better, but remember, you also need Series 7.

Don’t worry if this seems confusing. Keep reading. I will explain every detail. I will also show you how to choose the right exam for your career so you do not waste time or money. Let’s start with the FINRA Series 63 exam.

FINRA Series 63 Exam: What You Need to Know

Before we dive deeper, think about your job.

Are you only selling stocks and bonds?

Or do you want to help clients plan and invest money?

This question matters. It will decide whether Series 63 is enough or you need Series 66.

What Is Series 63?

Uniform Securities Agent State Law (Series 63) is an exam that focuses on state laws and rules. These laws tell brokers how to sell securities legally in their state. It is not about giving advice or planning investments, it is about knowing the rules to sell legally.

• Most states require this exam for anyone who wants to sell stocks, bonds, or mutual funds.
• The exam is simple compared to others. It focuses only on state rules and ethics.
• It is faster to study for and cheaper than Series 66.

Who Should Take Series 63?

Series 63 is for people who:

• Work in brokerage firms or sales roles.
• Want to sell securities only.
• Are not planning to provide advice for fees.

If you take this exam, you can start selling quickly. But remember, it does not let you advise clients legally.

Series 63 Exam Details

• • Number of questions: 60
  • Time: Around 75 minutes
  • Cost: $147
  • Passing Score: 43/60
  • Difficulty: Easier than Series 66 because it covers a small topic set

Important note: Skipping the details here could mean studying for the wrong exam. Series 63 seems easy, but it has limits. If you only take Series 63, you cannot advise clients or provide planning services.

Why Series 66 Could Be Your Game-Changer

Now that you know what Series 63 is, you might wonder: What if I want more options? What if I want to advise clients too? That is where Series 66 comes in.

Think of Series 66 as Series 63 plus the knowledge to advise clients legally. It is for those who want more career flexibility.

Understanding Series 66 Exam

What Is Series 66?

Series 66 – Uniform Combined State Law is a bigger exam. It combines state law knowledge (like Series 63) with basic investment adviser knowledge.

It lets you sell securities and give advice legally.

• You must take Series 7 as well. Series 66 alone is not enough.
• Passing it allows you to work as both a broker and an investment adviser.
• It opens more doors for your career. You can work with clients more fully.

Who Should Take Series 66?

Series 66 is for people who:

• Want to sell securities and advise clients.
• Want a broader career path in financial services.
• Already have Series 7 or plan to take it.

This exam is more demanding. It has more questions, takes more time, and costs more than Series 63. But it gives more long-term value.

Series 66 Exam Details

• Number of questions: About 100
• Time: Around 150 minutes
• Cost: Approximately $177
• Passing Score: 73/100
• Difficulty: Harder than Series 63 because it has more content

Warning: Not understanding Series 66 could limit your ability to advise clients. One exam plus Series 7 can open many doors that Series 63 alone cannot.

Scenario 1: Selling Securities Only

If your job is only to sell stocks, bonds, or mutual funds, Series 63 is enough.

If you want to sell and give advice, Series 66 + Series 7 is better.

• Pros: Opens more doors, covers both roles in one exam
• Cons: Longer study, more difficult, higher cost

This path is best if your goal is to work as a full financial professional and provide planning and advice.

Scenario 3: Unsure About Your Path

If you are not sure what you want in the future, consider Series 66.

• It gives more flexibility and future options
• You avoid taking multiple exams later

Important: Choosing the wrong exam now can force you to take more tests later. Make a choice that fits your future plans.
