This July, I graduated from the London School of Economics with a Bachelor's degree in Law. For those unfamiliar with the British higher-education scheme, law is an undergraduate subject at university (as is medicine, and a fair few other courses reserved for graduate schools in the US)... which surprises many Americans whom I tell this to, hence the explanation now. Also, for the most part, British universities make you study your degree subject exclusively (no 'majors' or 'minors'; just your subject), which also tends to make many Americans' heads spin.
In terms of entry requirements, law at LSE is apparently one of the hardest courses to get into in the UK. I don't know about other subjects but, in my year of applications, there was one place for every 17 applicants, so I guess I was quite lucky in my year. I got rejected from most of my other applications to other universities, so make of that what you will.
The course wasn't difficult, per se, but it was quite intense with regards to the volume and complexity of the reading involved each week. However - again, another quirk of the British university system - that the assessments were comprised entirely of three-hour closed-book exams at the end of the academic year, with nothing you do for the rest counting towards your final mark, meant that it was fairly easy to coast for most of the year, then cram in the weeks leading up to the exams. For me, that strategy worked wonders; for some of my friends, it didn't. People take to it in different ways, and it's harder to do in more scientific subjects than 'artsy' ones.
At the start of my third and final year (oh yeah, undergraduate degrees are three years in the UK - hope this isn't blowing anyone's mind!), I was offered a job at a corporate law firm upon graduation. (SELLOUT! I know...) In order to become a lawyer in the UK, after graduating one needs to take a program called the Legal Practice Course (or the Bar Professional Training Course, but that's a different diatribe for a different time), to learn all about the practicalities of being a lawyer i.e. what forms to fill out to sell a house, how to officially go about suing someone, the non-academic stuff of law. That's what I'm currently doing now: it's very different from LSE in that the days are more structured, the emphasis is on problem-based learning, rather than copious amounts of reading, and the pace is much more intense. I'm doing an 'accelerated' course, which essentially packs 10 months of study into 6, so that adds to the pressure, but it seems to be going OK so far. I'm about two months in and the work hasn't completely devoured me as of yet. If anything, I prefer this stuff to the work I was doing at LSE: for one, we have to learn basic accounting skills which means I CAN DO MATHS AGAIN!!! And filling in forms is proving quite satisfying in a menial way.
With regards to getting into my current course, I was guaranteed a place because of my job, but many other people don't have it so lucky. If you don't have a training contract or a pupillage (UK legal mumbo jumbo for 'work' as a lawyer) by the time you leave university, it's very hard - and expensive - for you to get onto a program like the one I'm on. It's really unfortunate.
