If you have a curve with an asymmetric bimodal distribution, is it considered a normal distribution? Or is it only a normal distribution if there is a single bell-shaped curve?

A normal distribution is symmetric and unimodol.
Therefore an asymmetric bimodal distribution cannot be normal.
But beware:
A symmetric and unimodal distribution is <i>not</i> necessarily normal. These are necessary but not sufficient conditions.
