These mods focus on college classes, teen jobs for YAs and aging among other things related to University. It was his answer to Squinge's Mega College Set (only at IS) that allowed YAs to live at home and go to college.
I looked at some of them to find out what they did.
Caveat Emptor: These mods are only for Apartment Life (AL). No lame requests to modify them for other EP/SPs. They come as is. Take it or leave it.
ah_AL_YA_collegeandelderjob - Allows YAs and perhaps elderly adults to obtain regular jobs. Probably useful if no teen jobs aren't modified for YAs. Test this out to see what it does at your own risk.
ah_BaseGame_YA_Job_Conversion - Teen jobs from Base Game converted to YA jobs to accommodate YAs' class schedules and exams.
ah_ChristianLov_JobInfoTool-TEST - This one was a testing mod (based on ChristianLov's JobInfoTool mod from MTS) with additional functions to allow YAs to view their job status, career level and whatnot while the YAs are at college. I believed he had a finished version, but I couldn't find it on my storage drive. This mod used a painting (medium sized painting with rainbow-colored oils and dark frame).
ah_ClassStartBCONs - Start classes as early as 8 AM and finish classes roughly before 1 or 2 PM. Did not see anything about exam start times.
ah_Freetime_YA_Job_Conversion - Teen jobs from FreeTime (FT) converted to YA jobs to accommodate YAs' class schedules and exams.
ah_HarderGrades_Professor - Makes it tough to score a grade grade with a visiting Professor regardless of romantic or social interactions. Potential for YA to fail randomly.
ah_HarderGrades_TermRequired - Makes it tough to score a good grade without writing a term paper. Potential for YA to fail randomly.
ah_NoAgeYA - If I recalled correctly, this mod addresses the hidden aging issue with YAs at Uni when Inteen and ACR are used (together or separate) in the game. This mod stops YAs from aging. They didn't age originally by Maxis design, but with ACR, they started aging normally as adults once they age up into YAs at college upon their arrival. What happens is that when YAs graduate and become adults, their fertility scores drop to 0%, rendering them unable to have children and are marked as "elderly adults".
ah_Seasons_Job_Conversions - Teen jobs converted to YA jobs to accommodate the YAs' class schedules and exams.
zah_AL_cd_higher_bills_tuition - Higher bills plus tuition. The bill is at $500 (general), and the tuition at college gets added to the general bill ($200 per college student in the active family either at a dorm or college resident lot). On regular resident lots outside Uni, the bill gets figured based on the lot value, not on anything else. The bill becomes ridiculously cheap over time as the lot value deteriorates. Does not use Mansion&Garden bonuses to cheapen the bills (solar panels, anything "green"). Do not use this mod with other bill mods made by AH. They all are the same with the exception that this one gets tuition added. Your YAs will be miserable paying their bills with this one guaranteed.
The mods above are finished versions and are "as is". Warranties went out back in 2009.
