my friend was telling me about that since washington is having a coronavirus crisis and that seems like a nightmare  my only pieces of advice since i have a couple online class that i’ve worked out a routine for is to set up your day so that you force yourself to study with at least one other person in the class everyday at a set time that you do not allow yourself to go back on maybe do this with each of your classes with scheduled extended break times because adhd=breaks needed communicate with your professors your concerns if you don’t have anybody else to study with maybe find somebody that you can spend your time for a period of time that will encourage you to keep studying while y’all are together my boyfriend does this for me and is really firm about it so it helps me a lot having an external force there to encourage you to keep working is what helps my adhd brain the most which goes right along with the idea behind in-person classes  also get an accountability buddy that you can text andor hangout with one of my best friends in college also has adhd and we hold each other accountable for doing our work and remind each other of upcoming assignments it’s really been helpful
