So, during my second year, I took a course known as Physics Problem Solving which was an elective for me. I did very well in the course initially, but my girlfriend broke up with me which led me to a downward spiral of depression. I realized that the emotional stress along with the coursework (each homework assignment was 25 pages) was too much for me and I pass/failed the course. I thought that since this class was only taught as a class at my college along that it may be interpreted by other colleges as a pass/ fail course. I did well on all my other courses that semester, I got all As. Every other semester I also did just as well. I'm at the end of my third year and I have a 3.94 major GPA and a 3.91 college (without silly high school college credit) GPA so far. I am acing upper level class coursework. I don't recall ever receiving anything less than an A- in any of my physics coursework, but I feel this will damage my transcripts beyond repair. Maybe I am overreacting, but for those who handle admissions would this damage my chances to go to a top grad school?
