Original post by BalerocNo. There isn't. That's what you came on the forums to ask, so you got your answer. If you refuse people to give advice and guidance, then that is to your great detriment.
But, your question will be next: "Why?". Why? It's obvious to everyone reading.
1. You have no motivation to complete the Law degree.
2. You are achieving average/mediocre grades in the first year.
3. You have chosen a degree with the intention of getting into an industry specifically money, rather than choosing a degree you are interested in.
4. You are studying at one of the most difficult university's in the country.
First, let's begin with motivation and your grades. Your average grades aren't the issue. Your average grades and poor motivation, in combination, is the issue. As you progress in your studies, you will require more studying in year 2 and 3, requiring more papers and case studies, more tutorials, more homework, more subtle understandings and external research is needed. The fact that you only achieved 63 in your first year with no motivation, will be your peak. You are unlikely to achieve any higher because you lack the motivation to research further into the subject, which means your grades will suffer even further as you progress into the second and third years, so you will be doing the absolute minimum - which is not enough. So, I would predict you are likely to end up with a 2:2, or a third based on your motivation levels by the end. Some motivated students at Oxford don't achieve a 2:1 at the end, so you should reconsider whether this is for you.
So, your first year grades will be predicted to be the highest you achieve based on your motivation level, so I would expect a decline in grades as time progresses.
Studying a degree with no interest will be your great detriment. You are unlikely to achieve a 2:1 by the end, and so your job prospects will suffer more by studying something you hate. If it was a few months further of studying, then the obvious recommendation would be to continue. But the fact you are in your first year, is not an ideal situation to be lacking in motivation.
Therefore, your job prospects will be massively affected, and I predict you will achieve a 2:2 at best, and possibly lower. So, your job prospects will be lower than if you changed to a degree that you had a greater interest, but slightly less prospects, as you could end up achieving a much greater grade, and that would consequently result in greater options being available.
It's up to you, but I would advise changing degrees to a different subject.
