is there away to add a skip botton to are assignments. specially when we get stuck on a question?

with us being allowed to skip a problem, that allows us to be graded for the work we have already done. without it we waste a lot of time. doing the other work and not able to process any further. we also get uncompleted work. that's not really right.

Does your instructor have quizzes set up so that students cannot move to the next question until they answer the current question? They can change that on their end, but they might have a reason for having quizzes set up as they are.

I am not sure what you mean by getting incomplete work. If I understand correctly, if you do not submit a response, it is fair that you do not get credit for the question. It would be better to submit a response, even if it might be wrong; at least you stand a chance to answer correctly. By leaving it blank, you will definitely receive zero points.
