Can a bad last semester prevent me from getting into grad school?
Admissions decisions will be made based on your application materials and any sort of interview process that a given program uses; this will all likely happen before the semester is over so you won't have any grades finalized before then.
If you're accepted, you will get an offer that states reasons the offer can potentially be withdrawn. It's likely there to be some sort of clause that indicates the offer is conditional on completion of your current degree, and it may be written more broadly to something like &quot;satisfactory academic progress&quot;. So yes, if your bad semester prevents you from graduating, it likely will prevent your admission. There's a chance possibility that a poor semester that doesn't prevent graduation could also affect your admission, but that will be entirely up to the program and nothing can be guaranteed. Given the ongoing pandemic I'd guess programs would be more forgiving of a recent slide. However, you'll want to make sure that you are able to be successful in the program, and if you are in courses now that will be relevant to your future you'll need to be sure you're staying on top of the material, no matter what your assessments look like. You also may see this as an opportunity to polish your time management skills, as these will be important in graduate school as well as in your current courses.
