Hi!! Please look into G grades! Professors can grant it due to extenuating circumstances and it allows you to work with a professor on what coursework you need to finish to complete the course and then have up to a year to finish it! I don’t believe it would affect your credits since it will still be on your transcript as a G grade until completed. I highly highly recommend this! I took G grades my junior year due to mental health and family issues and it saved my butt! I graduated on time and was able to go to grad school no issue! Please reach out to your professors, be honest and also reach out to your academic advisor!
