/sci/ - Science & Math

Please tell me I'm going to be okay for the 5 classes + 1 lab I'm taking this semester starting tomorrow. I've never taken so many classes before despite being a junior.
I'm stressed.
I'm not going to make it, am I?
It's 3 math classes and 3 engineering classes. I have a decent amount of friends spread across the 6 classes but a part of me feels worried. I know that this might just be the pre-semester hyper stress thing that most students go through.
Any tips/advice? I can't drop because all of them are vital fundamental classes.
Happy webm to keep myself a bit sane.
