Learning to study doesn't affect fun drain directly. It does, however, add +3 to the rate of Homework doing (base rate of 3), which doubles the rate at which you complete your homework, and therefore, halves the time you remain affected by homework drain. Having an instructor is an additional +3, for a total of +200% for having the study skill AND receiving help.
Ahhh... interesting. Well... maybe I'll tutor my dormies, so not only to get some money, which I know isn't much, but if anything to speed up their rates so that hopefully they won't leave so much clutter around the dorms.
As for the fun thing... maybe Ancient Sim has JenFlowers' sometimes faster fun homework hack? I don't think it affects dorm assignments, but at least for children/teen homework, I believe learning to study boosts speed, and consistently having good grades gives a tiny fun boost instead of drain. Well, here are the features of that hack which you can find
here:
FEATURES:
1: Serious Students (those with their Playfulness Attribute of 4 bars or less) will get a raise in their Fun Motive while at school and while doing their homework.
2: Students with an A-, A, or A+ will finish their homework faster and get a very tiny fun boost.
3: Students who are being helped with their homework will find that homework is not such a fun-sucker and their social bar should get a tiny boost.
(I added this in so that those student who just can't get an A, will at least have a chance to make homework a little easier for them..It doesn't really raise the fun bar, but they rate at which is goes down will be slower.)
.....and my favorite part....
4: Homework will only be given occasionally. When the student gets off the bus and checks their report card, you will then see a message appear in the right corner of the screen letting you know that they do not have homework that day.
Extra Notes:
1 - The fun increase (for those students who qualify) does not begin until the little blue progress bar begins to rise. The initial few minutes of homework will not be fun, but as the homework progresses, so does the fun.
2 - The student's grade will continue to rise even though they don't get homework. Grades are more affected by undone homework and missing school. I think mood affects this as well. Undone homework will still affect their grade. Make sure they finish the homework they do get.
3 - Some of the fun boosts will be very noticable and others will just keep the fun bar from dropping rapidly. It all depends on the combination of qualities your student has...serious, 'A' students, who are being helped with their homework will see the highest fun boost.
*****************
For those who are highly interested, I can give a quick summary of how homework speed works in the game without this hack:
-Homework speed begins at 3%.
-When the student is being helped by a family member, add an extra 3%.
-After they receive the memory that they have been taught how to study, add another 3%.
With this hack, all of that remains, but I have added a +8 increase to their homework speed when they are an A-, A, A+ student. (I got my Sim to finish his homework in about 1/2 hour - 45 minutes)
