What are signs of an intelligent woman?

In your opinion?

Imagine :
There are two women.
The one who thinks that she’s smart (and who actually is), works or learns hard and so gets good grades.

The other woman feels insecure in the near of the first woman and therefore downgrades her capabilities by saying she‘s not making it, not good enough or as smart as the first woman.
