Research shows that any AI writing detector can be defeated—and false positives abound.
Expect when you got teachers "Memorize all the formulas as it'll be on the test." and they don't provide the formulas even though in the real world, they just fucking look it up.
There is a reason for doing it that way.
I remember complaining to my dad about this exact thing saying that people just look it up in real life. He told me that in the end, the grade that I get will only tell future employers that I am more or less "teachable" compared to others.
What you studied, specifically, didn't matter. It's how well you learned the material in a short period of time, then cranked out correct answers in a time-pressure situation.
If you can do that quickly, you get a better grade, which tells people that you are a better candidate for a position.
