How can I face an online physics class while being busy doing a job?

Physics is something that you need to understand with proper concentration, if you’re doing a job, then it’d be a difficult task to understand physics in-depth, except for you’re Einstein. Physics requires strong knowledge of Mathematics as well, and Mathematics especially Calculus requires a lot of practice. So, just attending Physics lecture may not work. Try to spare some time for physics lectures.

Best of luck for your academics, I appreciate you’re working and studying at the same time. But if working isn’t necessary, focus only on studies.
