A calculator is available on this.
I recommend using paper to set-up your calculations.
This quiz is timed - 25 questions, 45 minutes.
This is a closed notes, closed outside resource quiz.
AI will be of little use to you on this quiz.
First attempt - If you score below a 70%, you may attempt this a second time, tomorrow.
Second attempt - all of your prior correct answers are saved. Your score is capped at a max of 70%. I'll take the highest of the two scores.
