I graduated in 2014 and loved my time there; in fact I still live near the area!
While Law has arguably one of the most gorgeous buildings, its only used for tutorials and not lectures. The lectures are dotted about the entire campus and the walk from the entrance (if coming from Wantage or Student Village accommodation) is about 25 minutes. If I remember correctly Stenton (?) is the best placed accommodation on campus close to the Law building, Palmer and HUMSS, but is also the most expensive.
For me, I severely lost my interest in 2nd year as I did not like the combination of modules that was set. 3rd year was much better as I could choose. Some of the lecturers were awful for speaking too fast (so you could not write notes) or just read off the booklets you were given. Tutorials are smaller groups were you had set questions to review and would discuss them. At times, there were group presentations.
Law has its own society and promotes mooting and pro-bono work as extras.
In terms of job prospects, I believe a lot of work has to be done individually. She will have to ensure high modules marks in 1st year, to ensure she can apply for good vacation schemes during 2nd year. These schemes are invaluable for both experience, and a chance to get given a training contract. Training contracts are highly competitive and only the best get them. Reading is not a top Law course, so she will experience a lot of competition from Oxbridge, UCL, LSE, Durham etc.
Personally, I have not gone into law itself but into Tax Advisory (through choice) however I do know a number of my cohort became paralegals, and I know of at least one that is now a qualified solicitor (but did a few years as a paralegal first).
Law is fiercely competitive and she will have to try and make herself shine from Day 1 to put herself in the best place to win a training contract.
