I mean... no hate but this doesn't sound like a case of college is useless. If you tried your hardest and failed out, then maybe engineering isn't for you. I understand the engineering curriculum is much harder, but the fact of the matter is, to be a decent engineer you should be able to pass. It'd be a different story if you were failing because you were disinterested and had much better things to do with your time, but if you were failing because you can't get data structures or discrete mathematics then maybe it's time to change fields.
