Good IQ Challenge, Unclear Subscription

I liked seeing my score and challenge level, but there’s a lot of confusion about the follow-up fees that users report.

Not Clear Enough About Fees

I completed the test and paid the small fee, but weeks later I had subscription charges appear. I think the site needs to be clearer about recurring payments.

Enjoyable Test, Billing Issues

The test itself was fun and mentally stimulating, but some users, including me, got charged more than expected afterward.

Be Careful With Payment Details

The test was interesting, but I saw charges on my account that seemed to be for a subscription I did not ask for. I had to reach out to support.

Mixed Experience

I liked the questions and challenge, but there’s confusion around the payment terms. Not everyone clearly understands what they are signing up for.
