In short, the field that you are interested is highly competitive. Although job opportunity is right there but the number and quality of applicants may well over your expectation. I know several Chinese who have completed PhD in highly quantitative subject in the best universities of UK (and almost none of you can compare with one of them academically) still find it difficult to land a job in your field. This reveal that academic performance is only a necessary requirement but there are whole lots of other traits companies are looking for. Among them, communication is one of the weakness for Chinese students. If your consideration has been too focus on your own academic ability, I would think it might be time to re-think your whole situation again. Since the finance you learn in the UK is either completely useless or similar in curriculum in China. If you cannot land a job here at the end, I would think that those 300 thousand may not be worth spending (unless your family does not care about squandering that amount). I would not see it this way.....In most situation, students are over-estimating themselves and squandering a big portion of their families' wealth. Of course, many people can argue to the end of the world that MSc is useful because they learn something.

However, learning does not have to be taken place in the UK. You can buy books from Amazon and learn all them at home. I am sure you can buy a library with the money you spend on your oversea MSc. If you want to learn the culture or interpersonal skills, that's fine - but you have to think whether 300 thousands to learn these things worth every penny you spend? Besides, the situation I see is that Chinese students are all hanging around with each others in the UK, how can they learn English culture?

When you take a look at the MSc program, you might be wondering why there are so many Chinese who has no working experience at all.....Isn't it the ultimate objective of a MSc course is targetting the working group rather than fresh graduates who have no idea what they really need in their future careers? MSc at best is the extension of your undergraduate study but even most of the materials in your undergraduate study will not be needed in your work. So why Chinese students are so rush to get more deeper knowledge which again may not be used in their entire lives!

To be honest, the most proper way to join an MSc class is by knowing what knowledge you need at work, research through different schools to understand which programme match your needs and make the decision thereafter. By doing this, you can at least have some sort of certainty that the stuffs you learn can help you in your career. It is not like closing up your eyes and spending 300 thousand without knowing the possible outcome at the end and yet forever saying that "I would not regret no matter what" in front of the others.

Therefore the only reason that justify an outrageous expensive (look at the currency rate of sterling!) MSc education is a high chance of getting employed in the UK. In this sense, one really have to do a thorough self-assessment in order to see whether they are competitive enough to land a job.
