I dunno about ace, but I think it'll be okay. It's on Tuesday via zoom. I have to answer questions about my thesis. I'm really nervous, but I know that it would take A LOT of for me to fail or have my grade pulled down.
I don't know what grade they will give my thesis, but the exam is basically for them to determine if a) I wrote it, or b) I should have my grade pulled up.
They can also pull it down, but that is really rare.
