What can you use in your personal statement?

You don't need to relate the subjects you're taking currently to your proposed degree programme at all. Frankly I would consider that a waste of space in your PS character limit. The admissions tutors already know if they are or are not relevant in terms of subject matter or transferable skills and don't need you to repeat that. You can and should just write about your specific interest in pursuing that degree (and if it relates to a professional field, that vocation as well). This may follow from things you have studied in 6th form but need not. You should do wider reading, and you should also try and read more than just one thing...if for no other reason than to actually gauge your own interest in the field. There's no reason you can't focus on one particular subdiscipline of the field in your PS if that's what you've read about. You don't need work experience for law. Also the work experience you've done isn't really relevant either.
An EPQ doesn't really add value for admissions purposes. Do it if you have a nice project that you'd still do much the same work on reading around and exploring and it fits the EPQ mark scheme otherwise. Don't do it if you think it's just something to add to your UCAS application and personal statement to get "brownie points" as that's not how it works and the time would be better spent just doing wider reading in that case.
For me, the concern here is that you've alluded to all these things you're going to write about but none of them seem to have much of anything to do with demonstrating why you are interested in that subject area and what you have done to engage with it. Writing potted summaries of your A-levels with vague allusions to legal implications they may bring up, doing unrelated work experience and vaguely linking it to the subject at hand, having only read one thing in relation to it (beyond your curriculum or otherwise apparently?)...these do not paint a picture of someone interested in law to me, but someone trying to justify applying to it because you wish to do the course for other reasons (which I suspect have a lot to do with perceived prestige and salaries associated with the legal profession).
I would suggest going back to the drawing board and starting with the fundamental question of why do you want to do a law degree. Bearing in mind that a) you can become a lawyer with any degree and b) the study of law and the practice of law are different things. There's plenty of time to do a lot of reading around the area over the summer and to actually understand what it means to study law, and also what the practice of it is really like. As well as to actually explore the field as an area of academic inquiry in itself.

Firstly, my interest in law has nothing to do with salaries or prestige, and I dislike that you've insinuated that. While I understand you're trying to help, I think you could have worded some of this better. Yes, I'm interested in commercial law, but that's not because I'm money hungry - it is possible to have a genuine interest in the commercial sector. I only discovered that after visiting a commercial firm.

I didn't talk too much about my work experience and how it relates to law because I don't want anything I say to be plagiarised, in case I want to use it. I'm not trying to mention all these things for "brownie points", I just wanted to show that I am actively engaging in legal affairs, since I don't study A level law. The reason I did work experience in a healthcare setting was to see the law working in practice. I am interested in healthcare regulation, so for me to gain knowledge from the professionals who have to follow these rules helped me understand the depth of specific policies (e.g. the extent of duty of care in regards to infection control and factors that could be used in defence against clinical negligence claims). I wanted to do my EPQ for myself. Quite frankly, I don't care about the grade, I just feel that this is a good opportunity for me to learn how to research and engage people while writing about lengthy topics. In regards to my A levels, the main points I were going to mention were a case study I did in psychology which about a specific person's international trial. This was a major trial as this person committed several crimes against humanity, that I do not wish to mention. I am very aware that I can become a lawyer without a law degree, but I have my reasons for wanting to study law, that are quite personal, so again, I do not wish to share them. I know what it means to study law, so no, I'm not someone who has just had this thought on a whim.

The main thing I wanted to know about was whether I should focus on only one or two subjects (including my EPQ) to talk about in my PS and whether I can use podcasts. Obviously, I will read more books, I just currently don't have access or the resources to find ones in either, the areas that I'm interested in or law in general.

I'm currently in Year 12 studying psychology, philosophy and politics. I want to apply to study law at university, and I have some questions about what I can include on my personal statement.
Firstly, I do have work experience, but not in law. My work experience is in general surgery in a hospital (and will be doing optometry work experience in the Easter), but I know that I can tailor this experience to law in my personal statement as I've already done it on a scholarship application and my teachers approved. I've also attended a networking careers day at a top law firm, so this is something I'll be mentioning too.
Secondly, I understand the general structure that most successful personal statements follow, and I have planned out elements of it, but the ones I have questions around are academics and wider knowledge.
For academics, all my subjects can link to law very easily and I have a few ideas or case studies that I can use to demonstrate that. I'm just wondering, should I mention all my subjects or would this be too much? I know there's a 4000 character limit so I'd like to know if it's better to focus on one or two more in depth or just briefly mention every one of them. I'm also thinking of doing an EPQ on either counter-terrorism in the UK or the rehabilitation of s*x offenders, so would that be better to mention instead of one of my subjects, or should I just put in all of it?
In regards to wider knowledge, I know most people say you should read a book - especially if the degree your applying to has a lot of reading in it. I do have a book about the ethics of organ transplantations that I can read and link to philosophy and law, but I don't know if I want to have this much focus on healthcare law, since my work experience is already going to cover this. I do like listening to podcasts (no, not just true crime), so I wanted to know, is this would be something I could include instead? I think I might benefit from this more, since I want to practice in commercial law within either a real estate or competition law practice group and I'll be able to demonstrate my more niche interests through podcasts. I'm really into agriculture regulation (within competition law) and real estate development, so I can definitely find some podcasts that talk about these topics, but I'm not so sure about books. I'm trying to keep my knowledge up to date as well, so as a politics student, I enjoy watching debates in different Houses about these topics.
If there's anyone who has done a personal statement (law or non-law) and can answer some of my questions I'd be extremely grateful! As well as this, I would love to know what course you applied for and what universities gave you offers, as I'm mainly targeting Russell Group universities.

Hi @bibachu
Firstly, if you can tie your work experience back to why you want to study law, then maybe include it eg. what did you experience during this work experience and what's a law perspective on this.
In a personal statement you really want to get across your passion for studying law as well as why you think you'd be good at studying it. Therefore if you do an EPQ make sure to include it as it demonstrates more university style work. You could talk about a particular area of law that interests you, and what other activities you've done to explore this area whether it be reading, podcasts webinars ect.
Hope this helps!
