I have developed a crush on this girl in my class. How should I approach her?

I am a freshman and we both don't know each other.We will be in the same class for 4 years.

I know this may sound like a stupid question but idk if I need to have a certain way I go about this since it is different from approaching someone in the university, bar,mall, other class.

I think I am confident and don't really care about any awkwardness but just like to do things in the best way.

Need some tips.
