Unethical charlatans who con money from children! (and adults probably). My 14yr old son recently noticed several charges on his bank account to Cerebrum IQ. It appears he completed an IQ test via a facebook post (fed to him) and in doing so unwittingly signed up to a 'free trial', not realising he was supposed to cancel within a certain timeframe. He had no email confirmation or any account information with which to alert him of this or to remind that the trial was over/ending. Since contacting the company the 'customer service' has been nothing short of appalling! I explained the error, they have consistently avoided answering my query, every time deflecting with automated messages designed keep me hanging on to the assumption they are "working on it". It would appear unethical profiteering is more important to Cerebrum IQ than doing the right thing. The amount of £25.98 (which has taken several months to save) is clearly far more important to them than doing the right thing in returning it to a minor they have essentially hoodwinked. I am also somewhat troubled by the 5star ratings for Cerebrum on all platforms as they all have the whiff of AI about them, read the 1star ratings, they all hi-light the same complaints.

Beware of the MAJOR SCAM
February 22, 2025

.99c test turned out to cost $50 after they started charging me $14.99 every WEEK. Nothing in the sign up said anything about this. Luckily after reading other complaints I caught it in time. If you are interested in starting a class action lawsuit lets get it going!

Amazing
February 14, 2025

I enjoys problem-solving, taking an IQ test can feel like an exciting puzzle, where each question offers a new challenge. A smooth and rewarding experience comes from staying calm, thinking critically, and managing time effectively.

After completing the test, and hsving positive experience includes feeling a sense of accomplishment, regardless of the score, because it provides valuable insights into strengths and areas for my improvement.

Cerebrum IQ is a SCAM
February 13, 2025

They are actually ZERO stars! I signed up for a 7-day trial for $.99 but was charged that PLUS $9.99. Didn't know it until my bank's fraud department contacted me. Tried contacting Cerebrum several times to no avail. I e-mailed every address I could find for them but still haven't gotten a refund. DO NOT USE CEREBRUM IQ! Tell your friends too.

INTERESTING
February 13, 2025

It's rewarding though in some questions with confusing answers
I'm kinda pressure in seconds.

At 71 years old now I've got a direct testing and result at 117 I.Q.

When I was 30 years old in 1983 on a self-assessment guided by Mensa London International instructions on I.Q. Testing I've got 146 I.Q.

Some months ago I've encountered the same testing I can't recall the name but my I.Q. Was around 140 +.
