Can I join Mensa with 129?
Mensa requires 130 (98th percentile). At 129, you're one point below the cutoff. However, given the standard error of IQ tests (3-5 points), retesting might produce a qualifying score. You're effectively at the threshold.
Is 129 the same as 130?
Functionally yes. The 1-point difference is within testing error and has zero practical significance. The only difference is classificatory — 129 is labeled 'superior' and 130 is 'gifted,' but both represent the same cognitive ability.
