This is a question that you have probably considered on more than one occasion already. It's possible that you need assistance with your college assignments because you are concerned about falling behind in the class or because midterms are coming up and you can't seem to find a way to budget your time and get all of your work done. In either case, you should consider getting some outside assistance. I am glad that you have made the initial move toward pay someone to do homework for the physics assignment, regardless of the circumstances in which you currently find yourself.
