1. Many people have said to save often. This is extremely true, but not only for bosses, save before fusing! You'll never know when you'll have an accident.
2. Maxing out your stats (ex. Courage and etc. is very important. Especially courage because there will be times when you'll need them when selecting certain options.
3. Max your social links, especially your friends' social links.
4. Play on Normal mode
5. After the first two bosses, the third boss and onward will no longer have weaknesses.
6. Defeat all extra bosses (You'll know when one has appeared when Teddie says there's another powerful shadow in the dungeon where you fought the major boss) because they have special items for your teammates.
7. Spend your days wisely.
8. Don't waste SP because you'll have a hard time to get it back(at least in the beginning. When you get fox he'll restore it, but for a price though. But even then, It'll still be a tad hard to regain it.) really easy to do so, so try to save SP. (It's easier gaining SP in P3 than P4)
9. Get Trumpeter when you can (one of the best personas you can have.)
Well that's all I have to sat
