It's not that Cengage doesn't have any helpful aspects, the immediate grading system (at least for my course) is quite helpful. But the testing system is absolutely terrible.
One of the most stressful things I've ever done. I had a breakdown during the exam because I couldn't get to a single sentence I was supposed to format because the dumb test bank had left a gigantic picture in front of it. Every time I attempted to move the picture so I could format the text underneath, the system would count it as an attempt and I wouldn't be able to correctly complete the instructions because the test was glitchier than a Bethesda video game.
Don't do it. Avoid this like the plague.
