Scots law is different from England. A solicitor qualified in Scotland is qualified to practice in Scotland, not necessarily UK wide - this is important to consider if you are considering settling. From what I understand, the process in Scotland is the same no matter level of degree: one year 'diploma' course followed by two years traineeship upon completion of the degree. The diploma course costs about £7000. Funding is available for 'home' students, however, who demonstrate academic excellence. The traineeship pays about £10,000/pa. Both the diploma course and traineeship are full-time.
Hours. Well, that depends. Everyone in the employment department of the major firm I worked in in Edinburgh worked the same kind of hours I did working legal in the US. I suppose it might be different in smaller firms, but everyone goes into realising it's NOT a 9-5 job. Some associates don't put in the time partners do, others are compelled to to become partners. Assistants - newly qualified solicitors - put in a lot of time, as do trainees (aka 'slave labour').
I'm starting an undergrad degree (my second) in Scots law in Autumn at Strathclyde and preparing for the long haul, as I wish to practice. Prior to moving here, I was a legal secretary in the US for 9 years.
