How to recognize if the scene has changed in C#?

So, I’m working on a game where it will go through different scenes (levels.) So, instead of making a separate script for a set score for each and every scene, I want to make a script that recognizes which scene it is currently, so that it can change the value of the score accordingly. Is there a way for me to do that in C#? Thanks.

you can use the scene manager
see here Unity - Scripting API: SceneManager
