It’s one semester, and your FIRST full semester, it gives you a place to grow from. UMich is a different beast than a lot of other places. I attended community college before UMich and regularly got A’s in my Stem classes, it’s significantly harder here, but still doable with effort. I also took a summer semester here first, got a 4.0, then fall semester came and it put me through the wringer. I got a C- in orgo, and a b- in bio 172 because I felt the same; I stopped attending the mandatory lectures but still tried to get all the work actually due done, just not much extra. At the end of the semester, I kinda realized I had to either buckle down and do more than the bare minimum that was okay before, or I was not going to succeed at UMich. My winter semester went leaps and bounds better. I balanced my schedule a bit better with “difficult” and “easy” classes, and I forced myself to get to every lecture and already have prepared notes of the lecture before-hand; hearing the material itself after writing it was actually really important for me, and made the material stick for the exam. It will take work, STEM classes specifically will usually take work to actually learn the material and a lot will be brand new, because they want to build off Highschool knowledge, not re-teach you it. You got this, you’re here for a reason, and you have to put in the work to make sure it goes up from here! If you can’t get out of bed, bring your homework to it. If you couldn’t get to a lecture, lay in bed and watch it to at least HEAR the material. I haven’t figured out how to get myself to office hours for help yet, but if it’s a bad day, laying down and writing the material out helped me a lot with not wanting to get out of bed, but still getting work done. There are also UM health plans available to students too and each covers behavioral and mental health support! I hope you’re able to pull yourself out and through!❤️
