Cerebrum IQ Test: Reddit Reviews and Billing Risks
Our verdict: do not enter card details for Cerebrum IQ unless you understand every price and renewal term first. Reddit threads and recent Trustpilot reviews describe people expecting a small one-time charge and then seeing recurring charges; those are customer reports, not a finding that every transaction is unlawful, but they are a serious reason to pause.
The search intent here is not an abstract discussion of intelligence. It is whether a checkout and a result are worth the risk. In 2026, transparent price and cancellation terms are the minimum standard.
What reviewers report
Multiple posts in r/Scams describe a low-price IQ result offer followed by charges or subscription terms the writer says were unclear. Trustpilot reviews visible in July 2026 include similar allegations about recurring billing. These reports are anecdotal and can be incomplete, so do not repeat them as proven fraud; do treat recurring, independent accounts as a reason to inspect terms before buying.
| Check before payment | Why it matters |
|---|---|
| Total charge today | A headline trial price may not be the total |
| Renewal date and amount | Recurring billing must be understood |
| Cancellation route | Save the instructions and confirmation |
| Merchant name on statement | It helps your bank locate a dispute |

What to do if you were charged
First, save screenshots, confirmation emails, terms shown at checkout, and your bank statement. Contact the merchant through its published support channel and request cancellation in writing. If you believe the charge was unauthorized or the terms were not disclosed, contact your card issuer promptly to ask about its dispute process. In the United States, consumer assistance is also available through the CFPB and state consumer-protection offices. Do not publish card numbers or personal data in a review.

A safer standard for online tests
An online test can be a reasonable low-stakes estimate only when its purpose, score limitations, and cost are visible before payment. Our site lets users take the questions first; detailed results are a clearly priced one-time purchase, with no auto-renewal. That does not turn an online score into a clinical assessment, but it removes a billing surprise from the decision.
Read the checkout as carefully as the questions
Before any low-cost offer, look for the total cost, currency, trial length, automatic-renewal language, and the exact date a later charge can occur. Take a screenshot before selecting the payment button. A checkbox, linked terms, or text placed beside a button can be legally important even when it is visually easy to miss. If a site changes the price after you have spent time on the quiz, stop rather than treating sunk time as a reason to pay.
The specific Cerebrum reports found in the search results describe offers around one euro, pound, or dollar followed by claims of larger periodic charges; amounts and circumstances differ by reviewer, region, date, and product. That variation is why this article does not state a universal current price. Verify the screen in front of you and do not rely on a social-media ad, an old review, or a search snippet.
Keep the evidence useful
If you contact support, state the transaction date, the merchant descriptor, the amount, and the remedy requested. Keep communication factual. If a bank asks whether you authorized the initial payment, answer accurately while explaining what renewal disclosure you saw. A charge dispute is a bank process, not a guarantee; save records and follow the issuer's deadlines.
Accuracy is a separate problem from billing
Even a perfectly clear checkout would not establish that an IQ result is accurate. A useful IQ estimate needs evidence about item design, norms, scoring, and measurement error. Consumer reviews about charges do not answer those psychometric questions, and a flattering score does not make a pricing model trustworthy. Keep the two decisions separate: whether to provide payment details, and whether a result is suitable for the decision you want to make.
For an informal test, look for a stated score scale, a clear explanation that the result is an estimate, and no claim that it diagnoses a condition. For formal decisions, use a licensed examiner. If you decide not to pay after finishing an online quiz, that is not wasted effort; it is a sensible response when the commercial terms are not clear.
Before you start: a two-minute safety check
Use a payment method with alerts enabled, and read the confirmation page before closing it. Search your email immediately for cancellation instructions and save the message. If a subscription is genuinely wanted, set a calendar reminder before the renewal date. These steps are useful for any consumer subscription, not an accusation about one company. They also make it easier to act promptly if what appears on a statement does not match what you expected.
FAQ
Q: Is Cerebrum IQ a scam?
A: We cannot make that legal conclusion from reviews alone. The evidence supports caution because many reviewers report billing they say they did not expect; read current terms and avoid payment if they are unclear.
Q: How do I cancel a recurring charge?
A: Use the merchant's documented channel, keep written evidence, and contact your card issuer quickly if the issue is unresolved.
Q: Is an online IQ score diagnostic?
A: No. A licensed assessment is needed for diagnosis or formal decisions.
