Sorry to hear about your experience. While I never had any technical issues that prevented me from inputting answers, I had temporary glitches (ex. There’s an error in Excel where when you backspace, it deletes the characters in the opposite direction and there were a few other issues with copy paste and other miscellaneous issues).
I’m convinced these errors cost me time and I wasn’t able to finish the exam. I wonder if in general, the CAS will contemplate the computer-based environment in their grading. Im aware that it does enhance things to some degree but the environment wasn’t identical to Excel.
Guess we’ll have to wait and see.
