@noeinstein777 Sometimes, for open answer questions (those with text input boxes) the hinted answer is incorrect, but the correct answer accepted. If the hinted answer is correct but not accepted you are "on your own" although I remember having tried some erronous answers and hit an accepted one once.

In case of multiple choice (either with radio boxes or any other relatively small finite set of answers) I have tried every possible combination without success. WIth 4 possible answers that is of course easy to check.

So there are (have been) definately questions where there was no way to proceed. Most often when I reported those these were fixed within a workday or two, but some in the Integrals have been there for a long time, some of them I reported while they exercises were still in the staging area, weeks ago.
