Hi, I did the LPC at ULaw, so I can answer on the following:
2. This depends on which mode and how many days you choose - part time vs full time.
PT over 2 years: can do weekday - Wednesday once a week, or 2 evenings or every other weekend.
FT 9months: 4 days a week or 2 days a week.
I studied it part time, weekdays - workload was manageable alongside my full time work but it required a lot of effort and hard work (it was a challenge but doable) The LPC is very independent so workload will depend on how much you want to get done. Obv there is compulsory prep reading and tasks you have to do but you can choose what is best for you - do reading before or after class, closer to exams etc.
I know people who worked part time and studied it full time - I think this is quite intense because then the workload is full on!
3. Yes mostly open book - for each core module there was an open book written exam (80% of mark) and closed MCQ exam (20%)
For electives - open book exam and coursework
I don't think the actual exams were more difficult but it was tough to revise for an open book. Obv for the core you had the closed book so you had to memorise regardless. You need to really be organised, notes need to be good, checklists for pre-planned answers for exam questions, loads of MCQ practice, text book tabbed, folders organised and tabbed.
After my law degree and the amount of revision i did, I don't think I wanted to go through it again so I guess I preferred open book.
4. Moorgate is lovely!! I studied in Bloomsbury but some of my exams were in moorgate and I preferred moorgate library so would go there. The library is awesome and the building is larger than other campuses (bloomsbury and bpp).
I would recommend you go to open days and get a feel - I did this and enjoyed ULaw more than bpp so then made a choice. Also, look at elective choices and career services provided.
Let me know if you have any other qs or need help
