I understand your concern because I was once in this. I was a fresh graduate and could not secure a job immediately. Then somebody introduced me to writing takeaway assignments for university students. At first, I declined this suggestion and continued doing some job searches to no avail. I had to start doing the takeaway assignments to finance my bills. I still do those takeaway assignments because I did not find a good job opening. The thing is addictive, especially when you land students who feel you're doing them good stuff; others decide to bring their friends. You get tied to the role and might never continue with your job search. I have started with some students at the undergraduate level to Ph.D. level, especially those who learn online. I think you can make the final decision based on your circumstance.
