Yes, you are being scrupulous. Have you started counseling with your priest for this as has been suggested a number of times already? You aren’t going to get better until you get help. You cannot come here and ask if every thought passing through your head is a sin.
Thinking about something and then not doing it is in no way sinful. We can’t even say for certain if actually using Google in this case would have been sinful-- i.e. cheating. You didn’t state anything regarding the directions or parameters of this quiz. It seems it was an at-home quiz, or some kind of independent study. Did the directions say it was “closed book” (i.e. you cannot use any materials), did they say it was “open book” (meaning you can use other resources to find answers), or were there no directions at all? This matters. If it was a test you were supposed to do with no help or resources, you were correct to stop and not use Google.
You also don’t say the rewards of getting a “star”. Is it a grade or is it simply self-satisfaction? If so, how does looking up the answer when you don’t know it give you satisfaction of achieving a “star”? If your motivation is just to get the “star” even if you don’t know anything at all-- then I would say you need to reflect on the real purpose of education, which is to learn and not to get “stars” from a computer program.
The correct course from the learning perspective would have been to stop, go back and study more on the ones you missed, then take the quiz again without help. Typically this kind of quiz is a self-check to help you identify what you don’t know so that when you get to the final test you will be prepared. Just doing the minimum for the correct answers circumvents this learning process and only hurts you in the long run.
