So my Sim did the Language and Literature degree from Britchester University, very confusing class schedule with some classes overlapping in times... so I can only guess that's a bug, cause if it's designed on purpose it seems an odd choice.
The specifics:
Sim Name: Jenny Straud
Sim Type: Human/Witch
Degree: Language and Literature
Schedule: 4 classes a term for 3 terms
Housing: Student Housing on the Britchester side for the first 3 terms, and private housing for the final term.
Scholarship: No
Result:
B- Degree and a few unexpected bonuses in the family inventory.
If you decide to do the degree and go into Law once you graduate, make sure you don't throw away the computer they give you, as you need it for the career path and cannot buy it in the shop, The degree gets you a level 4/5 depending on your final GPA. *edit* The computer for Jenny was a pre-job starting task where you had to look up something on the archives, unfortunately outside of university nowhere else has the archive machine and after graduating couldn't travel back to one of the university lots to use one due to no longer being a student there.
Also, good advice is to save after you graduate, and once you move out as well... cause I had to restart my game after accidentally killing my sim upon her return from university (oops!!)
No matter the degree you choose if you go into the relevant career path, don't accidentally delete the items. Will update this as the career progresses since there currently is no guide for that career path.
