I’m sure I’m not the only person who used the College Board SAT question bank and forgot to uncheck the “show answer and explanation” box before going to the next question, spoiling the next answer for me. To fix this, I made it so that my chrome extension will intercept the “Next” button click and display an alert if the box is checked! It was kind of hard because the check boxes on each question have a different ID and going to the next question gets rid of the event listener my extension adds, but I found out that the active check box is the last in the array of checkbox elements, so I was able to target that.
