“I took an official Mensa test a year ago and scored 131. BrainScale gave me 134. Impressed by the accuracy — and it's completely free. The domain breakdown is genuinely useful.”
“The questions are seriously challenging — way harder than other online tests. My score of 121 felt very realistic. Took 35 minutes, very smooth experience.”
