What've you done to recover from a horrible semester?

Summer C is almost over for me. Taking two classes. Intro to Electrical is being taught by a prof that doesn't regularly teach this class so he's using another prof's notes, and his TA quite literally spends the time during the recitation unintentionally confusing the shit out of everyone in the class so that they don't know what to do with the quiz immediately after the recitation. He has the solutions for the problems written out ahead of time, but he has never referred to them. He will instead try to work it out in front of us while we try to follow along. It's a subject that I've never done well with when I've encountered it in my life before school, so I wasn't expecting to do great with it

The other class has been fairly decent up till today and it's the abrupt change in direction for it that's hurting me I think. Manufacturing Production, one of the things we have to do is visit a manufacturing facility that must be approved by the prof before we can even approach them. Afterwards we write a report. I've had three places approved, but the first two never responded, so I found a third and they agreed but were taking too long to write up the NDA that would allow me to write a report. While I was waiting on them company #2 got ahold of me and let me know that they could give me a tour.

Unfortunately they contacted me after the deadline that you can get approved for any company. I visit them anyway as the prof has (until now) seemed fairly reasonable. I found out today that I haven't yet run into the prof's zealot-like adherence to his own rules.

The end result is that I won't be able to use company #2 for the report. Basically my nice mid-range B is going to tank straight to about a 30% because of the penalty attached to not turning in a report, and I will get that penalty because of a third party's need to make money is higher than their need to help a student pass a class.

I've been doing well up till now. Retake the odd course here and there, but due to other factors in my life I... I just can't see recovering from this. Not right now. I don't feel like I can take a semester off either. I'm a student that came to college late in life.

I don't know what to do. I feel lost.
