You dont need ged classes, just take it. If you fail, community college will grant you to take classes in the first semester so that will count as your ged. Those classes can be taken online. Then next semester you can take college credits, if you pass the first semester. Zoom classes you dont need to show your face or even talk. The instructor will just talk and most students will ignore or sleep. When you take your speech class, try to take it online. They can let you submit a video in youtube so the instructor can watch it. Lab classes will be the hard ones. You have to socialize a little and are loooong classes and very boring. You can leave those for later. Senior classes require group projects so talking will be required a little. Check out ratemyprofessor.com, it tells you which professore are good. Read the reviews.
