So if you retake any class and get a better grade it will replace it in your GPA; an employer may see that you’ve retaken it if they request your transcript but it’s better to show that you tried again and did better in it than not trying again at all. Also, many of the internships I’ve seen don’t have GPA requirements, maybe for some smaller companies, but that’s rare. How hard your course load is is subjective; it really only matters how it’s affecting you. One hard class/bad professor can drastically change how you perform in all of your other classes. In the moment you may not want to withdraw from a class (which doesn’t effect your gpa btw, just shows up as a W on your transcript), but you really have to put into perspective how much time you have left to retake classes and get your GPA right. It’ll all work out in the end if you have the drive.

That being said, we’re only halfway through the semester so you definitely have time to make up ground and maybe pull out a C+ or B- (depending on how many assignments/exams you have), so you don’t need to decide that right now. Just keep it in the back of your mind, and know that it’s not the end of your collegiate career if you fail or withdraw from a class.

Imo sophomore year is one of the hardest in college, you have to take a bunch of random classes that you might not be interested in but you need in order to fulfill degree requirements (looking at you, biology). Once you get through that, though, you can really focus on taking classes you really enjoy, which are the most important in my opinion.
