I need some serious advice

Just finished my a levels, Law, Biology and Chemistry. I think I’ve achieved an AAC at best and a BBD at worst (I think I’m going to get an AAD). I want to become a lawyer, but I am unsure of what the best course of action would be to take now.
Very brief details I know, but I didn’t want this thread to be specific and just wanted advice on EVERYTHING ranging from what: University, extracurricular activities/tasks should I do to maximise my chances of employment after graduation, if I should do a different course at a higher ranked University and if so how can that then lead onto a career in law, if I should go to a lower ranked Law University and how does that affect me. Literally any advice that would be relevant to me in anyway regarding my situation would be highly appreciated, and any things that I could do to better my chances at a career in a legal profession.
If I do go on to study Law at University (which is my current plan, but I am open to any advice on taking a different course to go down another route to becoming a lawyer) I know I can get a First, and I know that sounds very overconfident and a little far fetched, but Chemistry is/was not my subject and my grade from it is the main dilemma in my situation. I do truly believe I can achieve the best of the best grades at University because I genuinely love learning about the law, and it is my kind of subject. Any advice would be very much appreciated.
Also, information about the JD and LLM routes is very useful for me to know, specifically the pros and cons of each one and the timeline of each of these.
Regarding an LLM, if I did go to a lower ranked non-RG Uni and studied law (LLB), is it possible to then study a masters at somewhere like Cambridge, Oxford or one of the best Universities in the UK, if I was to get a first at LLB, and if so what other things can I do throughout my LLB studies that would strengthen my application so I can compete against the top of the Russell Group applicants (I know the university matters a lot, especially in law, but anything that could bridge that gap in the slightest would be highly appreciated). Thank you for reading this long-ass thread lol.

I think you should resit your A Levels as they don’t sound as they will be at the level that many leading universities or law firms would look at.

OP, I assume that by JD you mean Juris Doctor, the American postgraduate law degree. Obtaining a place at a law school in the US is not easy, and the course costs are high.
In the UK, many law firms and sets of chambers are now assessing applicants university-blind. University rankings are much discussed here, but they are arbitrary, sometimes misleading, and make less difference when seeking a career than people may suppose. For example, some of the apparently qualitative measures used by league tables are in fact quantitative.
What matters is the quality of the candidate seeking a position. Graduates of the leading universities tend to have done well throughout the educational system and may be competitive in job applications because of their abilities, not simply because they went to university X or Y. The fact that such universities are hard to get into and do well at means that their graduates may tend to perform better than other candidates. To this extent, the name of a university (where disclosed) may send a message to an employer about a candidate, but sensible employers look at individuals.
An LLM may assist, but the classification of your first degree will still be considered. The best way to overcome somewhat imperfect A level results is to do as well as possible in your undergraduate degree,

I like to be positive but also realistic. Your academic performance to-date does not bode well with regards to the likelihood of you getting a first at university. Think carefully before committing to a course which could leave you £100k in debt without a favourable career outcome at the end of it.

University-blind assessment of candidates for training contracts and pupillages is not universal but it is something done by a number of firms and sets of chambers.
I am not sure what you mean by "stacked credentials". With a first, you would have a shot at obtaining a place on a postgraduate course at Oxford, Cambridge, or UCL, but you would be competing for such a place against people with firsts from those universities and several others, and those candidates might out-perform you.

When I stack credentials, I mean a CV full of extra curriculars, bags of legal work experience and on top of that a first. Is that enough to potentially entertain an oxbridge?

Oxford and Cambridge are interested mainly in academic performance and potential, so extra curricular activities and work experience won't make much difference to an application to study as a postgraduate, but may be relevant when applying for jobs. Do you hope to become a solicitor or a barrister?
It is hard to say what effect if any "degree washing" by way of an LLM/BCL has on an application for a training contract or a pupillage. I think that katana10000, who is an experienced commercial solicitor, has expressed scepticism in other threads that it makes much difference to training contract bids. From my perspective as a commercial barrister, degree washing doesn't harm an application, but I'm not sure that it adds much to it. An Oxford BCL or an Ivy League LLM might be of most benefit if seeking a London Commercial pupillage. Those qualifications do tend to get noticed.
For the Ivy League, there are Kennedy and Fulbright scholarships, but as you might expect competition for those is intense.
You might consider also a degree in a subject other than law followed by a GDL. That takes as long and costs about as much as a law degree plus one year postgrad. Every now and them interesting courses become available through clearing at good universities such as Exeter and Birmingham, to name but two.

GDL? Any information on this?

never going a uni in brum lol, exeter sounds good. But I do want to study law at llb and then I'm not sure, I was thinking llm but need more advice on the options.

QMUL sometimes has places in clearing.

Search PGDL (Postgraduate Diploma in Law).

Thank you! Just checked their qualifications (AAB) do you think in clearing I could potentially secure a place if I got an AAC (the C is in Chemistry and then As in Law and Biology)?

That would be considered if I got a 2:2 at Uni, even though I haven't even started Uni yet. But I highly doubt I will get that, but definitely something worth knowing, thank you!
