I had a feeling ChatGPT might be a good application for this... I just uploaded a transcript from one of my course videos and asked it to create multiple choice questions based on the content. It did a surprisingly good job, and only requires minor editing to get the questions to make sense! This is going to save me a lot of time!
One of the parts of writing multiple choice questions I find particularly challenging is coming up with wrong answers that sound slightly realistic. The good news is ChatGPT is great at that!
