I haven't seen Baby Reindeer, nor the interview, but this is appearing on my social media today, because of the "law degree at Aberdeen" aspect.
I did law at Aberdeen in the 1980s; I'd have been a year or two ahead of her.
To become a solicitor required a law degree, either a three year ordinary, or a four year Honours, followed by a post-grad year - The Diploma in Legal Practice, and then you had to find employment to do the two year legal traineeship.
I did an ordinary degree. I'd estimate that 70-80% of my year did an ordinary degree. The ordinary plus the Diploma was four years at university, and very few people wanted to make that five years if it wasn't necessary. Some of those who did Honours did so because they didn't want a career in law, weren't going to do the one year Diploma, but were using the law degree as an entry into a different career e.g. chartered accountancy training.
An ordinary degree in law, coupled with the post-grad year, wasn't a lesser degree; it was the normal route into a career in law. Most solicitors of my generation graduating from Aberdeen had an ordinary degree.
