WispaWhisper, er. your question on the Legal Practice Course, my twins did those same core exams (in their case with BPP) a year ago. Those core subjects are about 63% of the year's marks and probably the most important exams of the LPC course.
If your son attended the group sessions / seminars and did the work set since he started the course and particularly if he did well in A levels and at university (and is at either BPP or UoL - 80% of LPC students are at one or the other) he will almost certainly have passed in my view. My daughters both did the same course too and did fine over 10 years ago.
I have a 45 page pdf of the marks of everyone with no names (just numbers) from last July where everyone could look up their own results (as each person knows their number). I just had a quick look at it but it is so vast that it would not be easy to check how many people failed a particular January exam. There are definitely some failures on the list and some absent from the exam and failed, a 36% e.g. I just saw on page 1, but the vast majority seem to be getting good marks or at least passing. My twins worked fairly hard and gained 70% or over in just about everything and they are not Oxbridge genii. In fact they found the law conversion course harder than the LPC, which was also the case with my daughters.
For anyone else reading though most new trainee solicitors will not be doing the LPC as it is being phased out and will have to do the new SQE exams instead - there is a cut off date for whether someone must do SQE1 or LPC.
Good luck to everyone applying for solicitor training contracts. It is very hard. Even in my day I applied for 139 firms in London in the last year of my law degree and had 25 interviews before finally getting an offer in about Feb of the last year of my law degree whch was such a relief. I thought I was never going to get anything. I am probably the worst person at writing applications and doing interviews in the country. So although I know a fair bit about the system being a lawyer with 4 lawyer children I certainly I don't know the magic formula of what to write on application forms and say at assessments and interviews to get the jobs.
