Series 10 common mistakes
Series 10 · Understand the traps and how to avoid them.
Picks whoever is a registered principal as the approver for a new account, a discretionary account, or an options account - including the producing manager who opened or benefits from the account - instead of asking whether that specific person is designated and free of the conflict.
Candidates collapse two different questions into one: 'is this person registered?' and 'is this person the proper approver for this specific action?' Registration feels like a sufficient credential, so the conflict-of-interest screen is never applied.
What to do instead
For every approval question, run a two-column check: (1) what action is being approved, (2) who is designated to approve that action, and (3) is that approver conflicted. Learn approvals as an action-to-approver matrix (account opened, discretion granted, options trading authorized, communication used, outside activity disclosed) rather than as a list of titles.
Answers 'prohibited' or 'no action required' when a registered person takes an outside job, joins an outside business, or participates in a private securities transaction, instead of separating written notice, firm approval/disapproval, recordkeeping, and compensation-based treatment.
These three fact patterns look alike on the surface (an associated person doing something outside the firm), so candidates apply one blanket rule and lose the distinctions the exam is testing - especially that compensated participation in a private securities transaction pulls the person back inside the firm's supervisory system.
What to do instead
Build a three-way triage drill: outside business activity, private securities transaction, and gift/entertainment. For each, write the notice requirement, who approves, what must be recorded, and what changes if compensation is received. Rehearse until you can classify a fact pattern in under 20 seconds before reading the answer choices.
Swaps the continuing education elements - treating the Regulatory Element as the annual one and the Firm Element as the periodic one, or assuming the firm may design the content of the Regulatory Element.
Both are called 'continuing education' and both attach to registered status, so the calendar feels interchangeable. The distinguishing anchors (who sets the content, what triggers the clock, and how often) get memorized as trivia rather than as a contrast pair.
What to do instead
Memorize them as an opposed pair, always together: Regulatory Element - regulator-set content, tied to the registration anniversary, recurring on a multi-year cycle. Firm Element - firm-designed after a written needs analysis, delivered annually to covered registered persons, with a plan approved by the firm. Never study one without reciting the other.
Treats a verbal trading authorization from a customer as sufficient, or treats a time-and-price instruction as making the account discretionary, or approves discretion without the written authorization and separate account approval it requires.
'Discretion' gets reduced to a single definition instead of a test: who chose the asset, the amount, and the timing. Candidates also assume the customer's verbal permission transfers supervisory obligations away from the firm.
What to do instead
Apply a fixed three-part test to every order: who picked the security, who picked the quantity, who picked the timing. If the firm-side person supplies any of the first two, the account is discretionary and needs written authorization plus the required approval and account marking. Memorize time-and-price as the named exception so it never has to be guessed.
Logs a customer contact as a routine service request when the customer is actually alleging that the firm or an associated person did something wrong, resulting in an undercount of complaints and missing response, retention, and reporting obligations.
Candidates triage on tone and channel rather than on substance - an angry voicemail sounds like a complaint, a calm email asking to 'fix' a charge sounds like service, and the behavior follows the surface impression.
What to do instead
Use one gating question before any other analysis: does this allege misconduct, error, or wrongdoing by the firm or an associated person? If yes, it is a complaint regardless of tone, channel, or whether the customer asks for money. Then apply the complaint workflow: log, respond in writing, retain, and report on the applicable schedule.
Judges account activity by outcome - treating a profitable, high-turnover account as clean and a losing, low-activity account as a problem - instead of screening for indicators such as excessive trading, unauthorized trades, or activity inconsistent with the stated objective.
Profit and loss are the most legible facts in the fact pattern, so they anchor the answer. Supervisory red flags are comparative and require holding the account's stated objective and authorization in mind while reading the trade blotter.
What to do instead
Before reading the answer choices, write down the customer's stated objective, authorized trading level, and authorization scope. Then evaluate the activity against those three, not against the account's gain or loss. Practice on fact patterns where the profitable account is the violation, so the outcome bias gets trained out.
Confuses pre-use approval of a communication with after-the-fact review of correspondence, and misclassifies a piece as correspondence, retail communication, or institutional communication, producing the wrong reviewer and the wrong timing.
The categories overlap in plain English - an email is correspondence to one person and a retail communication to many - and candidates use the everyday meaning of the word rather than the audience-size and distribution test.
What to do instead
Classify on two axes before answering: intended audience (one vs. many; institutional vs. retail) and timing (must be approved by a qualified principal before use vs. reviewed after the fact). Build a small decision tree and run every communications question through it, then name the required reviewer and the required timing explicitly in your own words.
Concludes that a supervisor who delegated a task to a competent subordinate, or who had written procedures in place, is therefore not responsible when the task was not done.
Delegation feels exculpatory in ordinary management life, and 'we had a procedure' feels like a complete defense. The exam tests the supervisory system as a whole, which includes follow-through.
What to do instead
Answer with the full chain, not a single link: written procedures, designation of a qualified person, training, monitoring and follow-up, and escalation with documentation. If any link is missing, the supervisor's obligation is unmet regardless of who performed the task. Memorize the phrase 'duties may be delegated; responsibility may not.'
Selects an answer that would notify or update the customer about a suspicious activity report, or that shares the filing with branch staff, on the reasoning that transparency is good client service.
Customer-service instincts and general disclosure habits carry over from suitability questions, where informing the customer is usually the right move. The anti-money-laundering context inverts that default, and candidates do not switch frameworks.
What to do instead
Flag any question involving a suspicious activity report as a confidentiality question first. The filing and its existence are not disclosed to the subject, and access is restricted within the firm. When an answer choice involves telling the customer anything about an AML filing, eliminate it before doing any other analysis.
Answers the scenario as the customer's advocate or the rep's defender - choosing the option that best serves the client relationship or protects the producing representative - rather than the option that satisfies the supervisor's detect, escalate, and document duty.
Most candidates come from a sales or client-facing background, where the 'help the customer, protect the rep' reflex is rewarded daily. The exam asks what the supervisor must do, and the correct answer often requires an action that is bad for the relationship.
What to do instead
Before reading the options, restate the stem as: 'What must the supervisor do to detect, escalate, and document this?' Then eliminate any choice whose justification is client goodwill, revenue protection, or loyalty to the rep. If two options both seem compliant, prefer the one with a written record and upward escalation.
