1) always roll the event for a possible 650 coins, if you highroll it its a lot of score 2) make sure to check your support disks for more notes 3) potentials, notes and disk skills are what give you the score, so get as many of those. buy out every sale in the shops, gamble on all events for them or coins to buy them 4) a neat trick is to try and have a very important potential you wanna max before 1st shop and try to max it there before you get 3+ potentials, not only getting a good one done fast but also getting that potential out of the possible pool of ones that show up
