Is it suppose to take so long to max Academics? I mean I've had some big set backs in the beginning with studying because of getting tired in Tartarus or getting tired because of studying. (Once happened like 3 times in a row.) But it is 7/24 now and I'm still at level 3. The others I maxed out usually a week or more ahead of the S. Link Maxing schedule but I'm worried about this.
Is there away way I can make more time to raise academics or something? Or any free ways like with courage?
You will get some free automatic Academics boosts during summer school (8/10 to 8/15 - it's automatic, so you can't miss it). Also, after summer keep an eye on Elizabeth's requests. One of them, for a "Sengoku-era helm," involves talking with various teachers in the Faculty Office after school for about a week. None of those meetings "use up" your afternoon - and all of them give Academics points.
Scroll down just a bit until you get to the Attributes part of the Basic Gameplay section. It gives you the rundown of Academics, Charm, and Courage.
Note that there are a few small errors in that part of the guide. The "Smooth" rank for Charm is from 45-59 points (not 45-64), and the "Popular" rank is from 60-79 points (not 65-79). Likewise, the "Tough" rank for Courage is from 45-59 points (not 45-64), and the "Fearless" rank is from 60-79 points (not 65-79). Also, you get +5 points to Academics whenever you use the Offertory Box at Naganaki Shrine while in "Great" condition (and not +4 to Academics as listed in the guide). I kept a running tally of my attribute points while playing through the game, so these inconsistencies were easy to find.
I think it was more because of those vacations and exams and such. Once I was able to study again it straightened out. 8/18 I reached level 5. I should have plenty of time now. However, after that I got figure out what to do on nights I don't feel like grinding tartarus. I've already been leveling the devil and tower links at night.
