I'm trying to catch a Combee, So I want to know if I catch a female with a higher level 21, how do I evolve it?

Question

As you may know,
I'm trying to complete the Unova Pokedex
In Black 2,
I want to know if I catch a Female Combee,
How do I evolve it into a Vespiquen?
Do I have to level it up
With high happiness,
And If so what amount of happiness?
If not how?
Thanks to whoever answers! :)

Answer 1

All you need to do is level it up. Since its higher than 21, you just need to level it up once. It doesnt make a difference that its above level 21. There is nothing special that you need to do to evolve it like happiness. All you need to do is level it up.
