You Don't Know Jack

Each episode has questions on different category styles. For this trophy you need to get 3 of the questions that are of a "math" type category correctly. If you wish to do this quickly and avoid having to replay episodes in order to attempt to get questions on this category correct, then you can use the answer list (Here) to get the correct answer to everything (therefore, you should get 3 music questions correct by the end of all 10 episodes). Once you get the 3 questions correct, the trophy will pop!
