is it worth getting skates?

see title!

i’m taking a beginner class right now and it’s my 4th week so far. i know im not passing my test (lol it’s next week and i just managed a two foot glide and getting off the wall comfortably), but i made the deal with myself that i would buy skates if i passed the class. skate rentals are free with my class right now. is this a foolish thought? i literally feel like there’s no point in me buying skates if im not going to pass and move up into pre-alpha, and when im not as comfortable yet compared to everyone else in my class :/
