I use MindTap Cengage and SAM. This has been the worst class I have ever taken. Consistent technical errors and then when I reach out to tech support they tell me that they cannot do anything. It errors out during tests and kicks me off of the page, I call tech support and they tell me they can't do anything because the exam is closed. Just today I submitted a 50 point assignment and it tells me I got 0/50 when I know that is not correct. At this point we are 8 weeks into the semester, I know how to type into an excel spreadsheet. The man I spoke to in tech support told me that because he sees a few errors that he is assuming I did actually get 0/50 correct. We get three chances to edit and perfect the document. Sure I would have a few errors but not 0/50. They are worthless.
