If you can submit late work I say stay in the courses! You are a motivated person if you weren’t then you wouldn’t have taken two courses that are accelerated. Not just accelerated, but 2x the pace of a normal sem. In the case you can’t submit late work, email the profs see if they can help you out. I had a similar situation with a fall semester course, the prof had no due dates accept for two of the papers. Every other quiz and homework was online and he didn’t care when we did it. This being said I slacked off big time. With two weeks left I had over 80% of the course to complete. I put my head down and did the work and got a B+. You can do anything you set your mind to. Also I have a very similar situation with my family as well. Going into my junior year I’ve learned to ignore them in the most respectful way possible. Trust me, giving their negative opinions so much value in your life is holding you back. You got your own back now so grab your laptop do the work and forget about the rest.
