Good evening Heyuri.

I am trying to focus for an exam but I realized I won't pass it without cheating and I already failed it a week earlier once. There is no third attempts, and the second one is in around 15 hours.
I figured out a method to that not even the twelve divine generals would not know in an eternity!

PREREQUISITES:
1. Guy would let you go to restroom.
2. Questions are handed on a smaller print, like A5 size.
3. You can have jackets or long sleeve during the exam on.
4. Have an item to 'engrave' text onto a sheet (I will use a screwdriver).
5* Additionally bring a clipboard.

METHOD:
1. Before I give up on what I am able to figure out, it could work without risking.
2. When I give up, I hide my print with questions rolled up in my sleeve so that he does not notice (the force of the sheet trying to unroll itself will make it stay firm in my sleeve).
3* As I quit I close my clipboard so that nobody can know whether the questions disappeared (its better to have it than not).
4. I claim I urgently must go to restroom and so I exit with the questions.
5. In the stall I lock myself inside.
6. I get the question sheet from the sleeve
7. I take a picture of it
8. I drop it to ChatGPT and make it calculate for me
9. As it solves my questions I take out the screwdriver and engrave the solutions onto the question sheet
10. When I'm ready I return within some 5 minutes*
11. Just before entering the hall I place my sheet in my sleeve in a way that pulling it out takes no time and no sound
11. I enter the hall and take my seat
12. I open my clipboard and make some noise to recover my sheets with engraved answers and keep writing
13. Win?

*5 minutes - to claim I had to take a seat there. A good excuse is that during peroids of high adrenaline concentration your organism pumps all energy into muscles and blood, leaving digestive tract without much power and so your feces are closer to liquid than anything if prolonged. I will use that excuse if he gets suspicious. A good thing is to leave in somewhat hurry and return the same way as well so it does not get suspicious. Spasming with a leg and doing muni muni to your face is indicative of stress, do it before quitting.

If you write without ink (engrave stuff with something like a screwdriver) and the lecture hall has bad lights then nobody but you would be able to read it by the tiny shadows and light manipulation shapes that indents leave so that you can read it from certain angles, but they are almost invisible from 50cm and nobody would figure out they even are there until you look specifically for them from 30cm at most.
