In Persona 3 Portable, you can choose between playing as the male or female protagonist. This schedule is specific to the male protagonist, as there are various differences between the two playthrough.

There are three social stats (referred to as social qualities according to achievements) in Persona 3: Academic, Charm, and Courage.

After performing certain actions, the player can level them up, with each one starting at rank 1, and maxing out at rank 6.


Certain social links have social stat requirements for progression, so it's important to increase your social stats as soon as possible. In addition to this, P3P added a feature to the Charm social stat which gives the player an additional social point multiplier that stacks with carrying a matching persona, making it possible to have a max of 2.25x multiplier!

Here are most, if not all the activities that increase your social stats:

Academic
*You'll want to stay awake when prompted to for class to gain academic points every time for this walkthrough (sleeping can provide you with great condition, but social stats is more important early)

Charm

Courage
*You'll be reloading your save fairly often to maintain your tired/sick status between days in order to visit the nurse's office multiple times after a Tartarus visit.

Having a persona that matches the social link you're interacting with will provide a 1.5x multiplier to all social points that you earn. Therefore it is extremely important that you carry a matching persona at all times (aside from a few, such as Devil and Sun, who do not require social points to rank up). While it's generally not necessary until after reaching rank 2 of any social link, it's best to do so just in case.

This walkthrough assumes the player will always carry a matching persona during the following activities:

• Meeting with a social link
  
• Fortune drawing at the shrine for a social link
  
• Accepting phone call from a social link
  
• Going out for a walk at night and meet with the corresponding social link
  
• Going to movie festivals and other activities with a social link

There may be times where you'll miss your chance to bring a matching persona, so here are some suggestions that will help avoid that from happening:

• Tartarus: Revise your personas before leaving Tartarus so you'll have the right personas for the next few days.
  
• Vacations: When there's a vacation, read ahead and see what personas you’ll need during and AFTER the vacation. You may have a meeting right after a vacation without being given a chance to switch out personas
  
• Sunday & movie outings: These happen right after you wake up and won't give you a chance to rearrange your personas, so make sure you have a matching persona the night before.
  
• Walk at night: Walking at night with Koromaru can grant social link points if you're meeting another social link during the walk, so make sure to bring that social link's matching persona.

A typical day in this walkthrough may look something like this:


The table is divided into days, with each day containing a day section and a night section. Each bullet point is one step you'll need to do in that specific order until moving onto the next (except for save & reload, where you need to check the message during date change for whether you need to reload).

For social link rank up responses and class/exam answers, numbers represent the option to choose, and "A" represents any.

"Points required for next rank" will always be displayed for each social link rank up interaction, and will serve as a guideline for you to know how close you'll be to the next rank up.

"Points got today" provides three numbers: (1) / (2) / (3)
(1) Is the base social points you earn assuming you do not have a matching persona or any charm
(2) Is the social points you can earn assuming you have a matching persona OR max charm
(3) Is the social points you can earn with a matching persona AND max charm

*Use points info to know whether you need to bring a matching persona.

Throughout most of November to January, you'll be given a lot of free time (especially at night time) to choose what you want to spend your time on. Here's a list of things you can do in terms of general priority:

1. Fix Social Link inconsistency (If you forgot to bring a matching persona or responded with the wrong answer, you may have deviated from the schedule and should use this time to catch up).
   
2. Tartarus (Requests, Missing Ones, level grinding).
   
3. Arcade for persona stat boost (2000 yen per visit).
   
4. Sleep / Spend time as a customer at Be Blue V (for Great condition, if you plan to explore Tartarus during the following night time).

*Don't forget you can go to the shrine and talk to the Inari to get your skill card duplicated at any time. It takes 5 days per duplication, but it doesn't cost you time and will be very helpful for building your personas.

Arcade Schedule

You'll be expected to complete all your Tartarus-related side quests (Elizabeth / Theodore Requests & Missing People) every time you visit Tartarus during this schedule.

For any non-Tartarus-related requests, check the Velvet Room each time there's a "Quest" task. That should help you stay on top of everything. And as a rule of thumb, the requests refresh around once a month.

For a more detailed breakdown of all side quests available in P3P, see this guide:
https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2920228498

On Jan 1, you'll be able to begin preparations for fighting the secret bosses, a couple of which are necessary in order to complete all requests. See this guide for more detail on how to fight them.
