I have a new problem, which didn't happen before the latest WeBWorK upgrade.
In a gateway/quiz, I set "Number of Tests per Time Interval (0=infty)" to 2, so students can take each quiz twice.
After a student's first try, I allow them to see answers and solutions in their first attempt, learn from mistakes, before trying a second time.
However, now a student can open a quiz attempt he/she took earlier, and fix the answers in the opened attempt (not a new try of the quiz), and then the quiz score would change! In other words, all students will get 100% in quizzes after they fix their mistakes in an attempt.
Which settings should I change to stop this from happening? I still want to give students two tries, though.
Thank you for help!
