I hate CASA

Today I had a Chem exam at the CASA gym. I found my seat and was ready to take the exam. But when I tried to log into blackboard on their computers it kept showing me a login fail. After trying to get help with no one able to figure it out, they told me to check out and reschedule my exam. I emailed my professor about it, and he said there was nothing he could do about it. He even said that multiple students of his were having the same issue. Now I’m worried that I will not even be able to take my exam because all of the time slots for tomorrow are full. They have to have a better way when things like this happen. I had a full meltdown because I was so afraid I would miss my exam and I still have to wait and see if I can even get another take at it.
