First day back on campus and I talk to this girl that’s a transfer student. She was very hot I’d say at least a 9. I saw her carrying alotta books so I was like “Yo you need some help carrying those books” and from there we started talkin about going to the new pool and I number closed.
The first day I text her for a while and she was saying I should introduce her to some people because she’s only been there for 3 days. I said sure we should hang out soon. The next day I text her on campus but she forgets to text back. Next day after that she notices me on campus and comes up and talks to me and gives me a hug. And she asked for directions to somewhere and she said she’d talk to me later.
The next day after that. She invites me to come to the pool with her but I was in class (BUMMMMER!!!) So I told her the next day I was free and that she should let me show her around. She says yes but the next day ends up cancelling on me because she said her friends from her hometown came and visited her unexpectedly so she had to hang with them.

What should be my approach on this girl? And what should be my next move?

The PUA thing to do would probably wait for her to initiate contact with you before you do anything but idk im new to this shit. but dont let her keep flaking on you. if you present youself as having less free time she will be more careful of canceling because she will haeto wait a while to see you again before you are free..
