My astro 101 exam is all done for tomorrow.  Things I incorporated to try to make it difficult to cheat on (not impossible, it's always possible to cheat):
-super short time limit, but open book/notes
-they have to answer each question before going on to the next, no skipping around
-questions are as specific as possible to my lectures
-anything with a written component is worded in a way that (I think) will be hard to immediately google, and hopefully will also be hard for chatGPT to answer.
