I keep trying to get past round 15 and higher but its just not working even with my guns upgraded and I don't use glitches. should I? or any tips

For me it honestly just comes with time.

I would put some practice into Exo zombies and just work on a pattern as far as when to buy perks, when to upgrade your guns, etc.

Next time I have a chance, I'll put some time into Exo zombies with you if you want.
