How to realistically pay for grad school? [Master of Public Health; has $57k+ debt from undergraduate]

I see a couple of people saying to wait. My biggest concerns are:

My loans probably won’t be paid off in 5 years…don’t even know what they’ll look like then cause they want like $500 a month but that’s a different story.

I’m kinda afraid they will reinstate GRE testing again. I think they paused it cause of COVID and I have a better chance, but if they reinstate it I’m done, I’m terrible at tests.

I’m also afraid that scholarships won’t be given to me at a later age. Do they actually do that?
