stop worrying about the grade (Score 1)

You're in college to learn not necessarily get good grades! Yes sometimes you'll have courses which require agonizing effort to get a c+ but it's learning and the process of learning that are the reward not your grade. So there's dozens of fields in technology where advanced math is central... There are just as many where it is ancillary. That's not the point. You're not going to do well in any tech field if you don't enjoy learning (especially If learning the particular subject pushes you to your limit and you don't like that)
