I would broadly prioritise like this: guarrantied rank up>school SLs>other daytime SLs>Bunkichi and Mitsuko

I usually do those, that are available on the fewest days, generally. Since school SLs get blocked many times in the story, they aren't available as often as normal SLs. Later when unlocking Empress, she's also a low priority because she's available a lot. Maybe you also should avoid maxing them for some time, so someone is always available in an emergency but I'm not sure, if that's nessasary

I recommend maxing out the Fool Arcana

Get school only ones first and ones that have other locked behind them(chariot, magician, emperor, strength, hanged) on Sundays do hermit or sun

Do the ones you care about

ALWAYS focus on school Social Links. If you can't rank up with someone, choose someone else from school to rank up. You can use your Sundays and days off at this point to gain extra points from Sunday dates and hangouts, or just going to the shrine.

You will have plenty of time to max out non-school links, including Hermit and Sun, so don't be afraid to use Sundays for extra school link points.

The S.Link schedule has been changed in Reload. Old guides will not work.

Because of the bonus scenes old guides won't be good anymore. If you want to do stuff optimally wait for a week or two so people can put up new guides.

It probably won’t take long for one to drop once the game is out

I'd assume guides will still be helpful for SL answers and optimising stat increases to access some SLs(unless the parameters needed have changed).

There hasn't been any mention of new stat-increasing activities, so they're still your best bet to use until more accurate guides specifically for Reload are made. You'd have to account for the new 'episodes' in the Reload that seem to only take place during the night at the moment if you're even interested in them. We'll also have time to actually work on our school SLs during summer break unlike og/fes/p3p, so that should help with the process becoming streamlined.

By my count, you have 25 schoolmate ranks needed from what you listed. Add in Fuuka who I don't see plus Mitsuru and Aigis who you can't start yet and that's 55. I think that's it for schoolmates. 55 with what you have left sounds doable, but cutting it very close. Granted, it's basically always close because of the way they set it up. 

Add in the others and it becomes a little more iffy. You only have 15 Sundays left and 10 Sunday ranks. I guess "Maya" can be done on another school holiday as well. I also can't remember if any if these Sundays have events that force you to miss a day. 

I don't know the exact number of days left from where you are. I only memorized January and a general idea of the after Mitsuru is available late November through December. 

Sorry I can't provide and exact answer either way, but the very rough numbers at least make it seem possible to me. 

Mostly availability. Prioritise school SLs because none of them are available during holidays/exam week except Empress during exam week.

There’s only 2 night SLs so prioritise increasing social stats at night to have more time for day SLs.

Some SLs are locked behind ranks in other SLs (for example you need to progress the Hanged Man to unlock Sun)

Social Links don't have special abilities in this game like they do in P5, but the ultimate personas are insane. One SL I would highly prioritize is the Star SL, the ultimate persona Helel has the skill Morning Star, the highest damaging multi-target almighty spell in the game. And it can be inherited via fusion, making it a must for god persona building.

There's also a special persona you unlock for maxing every social link in a single run.

Finish Yuko

Dying young man? I just started Reload, what does that mean 🙏😭

You're probably fine? You need a minimum of 75 free days to finish off all social links. Just make sure you do something productive everyday.

You have about 81-85 free days going forward. I counted out the silly holidays the game constantly gives you.

Focus on the school-only social links. Do the others during holidays

Try this

Finish off the Sun since there well be some extra days off to finish Hermit. I'll have to find a guide the next play through since I'm going to be short on three social links.

no

and i hope they dont

p5 confidant skills made the game far too easy.

if they do anything it would probably be the p4 route where its combat benafits for party members only

i hope they do but am fine if they dont

No.

P5R is much easier to max out than P3, mainly because the confidants are not mostly locked to daytime only and the calendar randomly skipping a week.

Take advantage of activities that give you bonus social stats because because there are some you will need to max.

Max out Temperance and Star arcana as fast as you can because they will help you save time

It is very difficult to max all your links on a first playthrough without a guide.

This is why New Game + exists, since your social stats carry over and thus you can more easily do social stuff since you don't need to devote any time to social stat upgrades.

There's a lot of time but a lot of things to do, so it's easy if you follow some basic guidelines but hard to do completely blind.

To avoid a detailed guide, you just need to prioritize:

1. Hang out with a time limited or critically important confidant: Chihaya, Kawakami, Yoshida, Maruki
2. Hang out with anyone else who will level up today (check the map)
3. You need to take at least one trip to Mementos between palaces, this might be a good day for it
4. Raise a social stat the best way you know how
5. Do something fun or hang out with a confidant who won't level up

You just need to find time to do darts and billiards to level up technicals and baton pass, and hang out with the Twins if you count that in addition to their social link (not all their hangouts can be done at night as some of the places they want to go are only open during daytime).

Just use a guide. I found a spoiler free one by just searching online. It just gives you a set schedule to follow each day without telling you any spoilers.

Buy this item after school, spend time with Ann, feed the plant, etc.

Helped me 100% all stats and confidants in one playthrough

Always have a matching persona with you and brute force Fortune (Chihaya, you unlock her around arc 3) as fast as possible since you can pay yen to see what a confidant's best answers are or spend yen instead of hanging out with them. Since you played P3R, you should know how good it is to save a time slot in exchange for yen. And on top she also gives more social stats. She's just overall OP for a full confidant playthrough.

Also, Yoshida, Akechi, Yoshizawa and Maruki are all time sensitive so also prioritize them.

I think it’s gonna be super ez, this game gives you so much free time, as long as you have a matching persona and answer well on social links you will get it

I’ve been using this one from powerpyx https://www.powerpyx.com/persona-3-reload-100-walkthrough/ So far it’s been doing me good. I’m still only as far as the High Priestess boss.

A few general tips for efficiency:

• On Sundays always do the Sun SL (or Star if Sun is maxed)

• On school days, always prioritize the remaining school social links (Priestess, Emperor, Lovers, Justivce, Fortune, Temperance, Empress, Aeon)

• In November a new shady URL unlocks that allows you to get extra social link points (no rank up) on the computer in the evening.

• In December there are 6 days where Empress is the only school social link available. It's recommended to save 6 ranks of Empress for this period.

• Save Star and Moon for the end of December/early January. At the end of December and early January there are several days of no school, which allows you to focus on them.

When comparing P3 to P4 and P5, it’s insanely apparent the devs never expected the players to go for all SLs in one playthrough - hell, in vanilla P3, Orpheus Telos, the reward you unlock for maxing out all SLs, wasn’t even a thing. It was only added in FES.

So no shame if you can’t max them all out in one playthrough. It’s a common sentiment that, even when using a guide, it’s still really hard to max everyone out.

Definitely focus more on school links.There are times where you’re off from school and can’t level up your classmates. So maybe maxing hierophant and hanged wasn’t the best call but you’re still making good progress. Leave Star and moon on the backburner as they’re available when you’re off from school. Use Sunday for sun obviously.

In November, a method to gain points for your SL will unlock in the club. Use this to avoid wasting a day where you don’t level up since you completed night links already. Use persona that matches for max points and try to avoid hanging out if you’re not going to level up, if you can help it.
