Struggling To Do Well With Online Classes

I know a lot of people probably have the same problem, but I’ve been really struggling to keep up with my school work and do well since we shifted to online classes. The time difference for the classes, technical issues, and just doing school in my room has been going horrible and my grades keep dropping. It’s stressing me out because I don’t know if I’ll be able to get into medical school if my grades drop that much. My school is only allowing us to pass/fail up to 2 classes and I don’t want to do that either because my advisor told me it doesn’t look great and you need to show resilience. I’m really trying and I just don’t know what to do anymore. I also go to college in nyc and I don’t know what I’ll do if classes are still online in September. Is it really a horrible thing to pass/fail classes if you are trying to get into grad school or get a job?
