I have 12 hydrostatics, but still get an F on its exam. since it recommends 6 hydro, this is prob not intended

That's... actually pretty impressive.
The game simulates four weighted coin flips when you take the exam, and the probability of getting an F with 12 hydrostatics is around 1 in 617,000 if my math is right.
Sometimes you study the entire textbook, and the teacher wants you to write an open-ended essay instead :D
Edit: I forgot that I changed the formula in the last update. The probability is actually 0.3–1.8%. Still impressive nonetheless!
