3 different psychologist have told me that I am "very" intelligent on initial meetings.

What does that mean?

I am no Einstein, I'm no beethoven, I'm no Neil deGrasse Tyson or whatever.

They also ask me if I write? No, I have a below average understanding of the english language(grammer, pronouns and ****).

People around me say I am very intelligent...

WHAT HAVE I DONE TO BE CONSIDER 'VERY" INTELLIGENT?

I feel like these psychologist and people I meet are playing a joke on me.
