Will mensa membership help get scholarships?

Mensa membership itself will not directly help you get scholarships. While it demonstrates a high IQ, scholarship committees are primarily interested in your academic record, extracurricular activities, essays, letters of recommendation, and financial need.

While a high IQ is often correlated with academic success, Mensa membership is simply one piece of information and is unlikely to be a significant factor in a scholarship decision. It's far more effective to focus on building a strong application in the ways mentioned above.
