You only need to pre-study for duties named "____ (Extreme)", "The Minstrel's Ballad: ____" or "____ (Savage)", if the party leader doesn't specifically indicate that people can join without foreknowledge.
Came to say this. Normal mode never gets difficult enough that you really need a guide to jump in. If you are someone who likes to watch them anyway(or watch them after to help you remember what you did) then i tend to recommend Mizzteq's guides on youtube. If you can handle the puns, she includes lots of actual video and fairly clear explanations. Her tactics arent always the best(she makes the guides when the content is new and the community might come up with better ideas over time), but they will help you through most everything.
