The quiz is “good” and it does a “fair” job of describing the “beliefs” of each faith.
However it is somewhat erroneous. For example the question on confession, I picked “All sins/wrongs to a cleric” as my answer, so I would get 100% Roman Catholic outcome.
If I answered honestly with “All sins/wrongs, but not necessarily to a cleric” I would not get a 100% Roman Catholic outcome. I would get 100% Mainline to Conservative Christian/Protestant and 96% RC/ 96% EO
This is because the writers of the quiz have the erroneous idea that Catholics must confess ALL sins in a confessional to a priest.
However, Catholicism doesn’t teach that. It teaches that only mortal sins must be confessed to a priest. Yes, it’s good to confess venial sins in the confessional and yes there is nothing wrong with it and it is encourage. However the Catholic does not have to confess venial sins in the confessional. Confessing venial sins can be done in the comforts of your bedroom.
