Is Law at King's College really worth it for an international student?

So I'm an international student who recently just received a conditional offer from King's to study Law and as you can imagine, I was super excited...until I saw the tuition. The course is £23 490 a year and subject to increases. WOW. I don't know why I never even bothered to check the tuition! My parents told me that since I got excellent grades I could chose whatever university I wanted and they would take me there, but I never expected the tuition to be so high. I assumed it would be around £15000 as that's just the general amount an international student is expected to pay. I guess I naively assumed that this applied to every course. Damnit. Not to mention accommodation at King's is around £250 a week. I know that if my parents really want to they could pay the tuition, but I don't want to stress them out and empty their pockets...that's a hell of a lot of money! Not to mention, they have my siblings to worry about too. So what I really want to know is...is King's College London really worth it? Is the law course that great? If I do well could it really open lots of doors for me in the future? Is this university and this course worth my parents coughing up over £23 490 a year?? Anyone currently studying at King's or a similar uni is welcome to reply. It's worth mentioning that I also got into Durham, Leeds, and have an interview with York next week. Still waiting to hear from Bristol. Thanks!
