Sorry
FacelessVixen. You wanted me to omit the details so I don't lead experiences too much. But well, others had other ideas.
This is cool and all but not really useful unless if you are going to guide everyone beat for beat through the perfect min-max. But then you will need to mention things like picking which season to get a 4.0 and which to skip classes for a week. Which is also not really necessary since you can get 55 of the 75 achievements without really min-maxing much. But not to say that your min-maxing isn't helpful though if that's what someone is looking for.

If you want to do Fall things early just take the early bird and night owl and it works as an improvised stamina.
Some want to start a relationship and get the sex earlier. And I know that means you forfeit the V-card and the "I studied the blade" achievement but it's better to play to get the experience you want at the time you want.
I mentioned it to someone else here but I really really don't like how "new game +" like the whole achievement system they added makes things.
I did my restart with v0.8b1 mainly for the achievement points and to check out what is how exactly possible.
I spent enough time in fall to only accomplish the
4.0 goal for Xavier's List, and I barely made it as baseball dude thanks to also picking the Night Owl perk in the last few days until the 14 days were over.
Sadly, the long infirmary rest times during events fast-forward so many game days that the 4.0 score is busted this way during winter-spring:
Player.History.update("lost_perfect_GPA")
At least I think this keyword here is responsible later to
not obtain the
Xavier's List achievement when you enter chapter 2.
The
V Card achievement(s) isn't/aren't really that terrible either. You basically only miss out the
first_sex event, but you can still fool around with the ladies using all the other actions except
Dildo Pussy (+self) and
Sex. That's really not much of a buzzkill. We'll have to see later with more introduced events, like threesomes, how this plays out.
One thing is for sure: I'm also going to enjoy this game a lot more later when I restart it again with that extra achievement (skill) point reserve without paying attention to any of these silly achievements.
Xavier's List will be rather a goal for chapter 2 but let's see.
I already reached 710 achievement points without leaderboard rewards and without even hitting level 10. I only still miss/want to do the A+ achievement.
Gosh, thanks to wasting so many skill points on perks, the level progression is still tad too slow for comfort with only stamina_boost1.
By the way if we are talking shop on the nitty gritty, do you know what the fail rate or mechanism is for Laura rejecting to do pool activities early on?
Can't say exactly at moment, but it's possible if together with others that Laura might lack enough friendship tier very early as she is blocked to gain any points until you have that talk about friendship and send her to Rogue. Afterwards, Laura and Rogue become Friends automatically (yeah, Rogue is already Friends to Laura from start but ignore that strange issue).
talk_late: 0/75 that is mainly studying at night or simply come over at night time.
temporary_follow: 0/100
follow: 0/200
sleepover: 0/150 (Rogue 175) but with more than one girl at same time only works with everyone as partners!
shirk_responsibilities: 0/300 (Jean 400). This is otherwise the major blockade preventing activities with Null!
