After a completed homework assignment, I was surprised to see that a question that I was certain that I answered correctly was marked as incorrect. When reviewing the question, I explained why my answer should be correct, and the professor hesitantly agreed to give students who answered the same (multiple choice) credit for the problem.
I sent him a reminder email to give credit for the problem, but he emailed be back saying that he only gave 50% credit for that particular answer to that question, and 50% for a similar answer to a separate question that depended on the same logic.
I am of the opinion that my answer deserves full credit. Is it worth bringing up to him again over a small amount of points?
