With many courses being so competitive, how many aspirational ones should I apply to?

I'm in year 12, studying maths, economics, chemistry and physics. My predicteds (basically my year 12 exam results) are currently:
maths - A
economics - A*
chemistry - A*
physics - A
I'm resitting maths in a few weeks to see if I can bump it from an A.
I want to apply for economics at uni and have totally fallen in love with the Land Economy course at Cambridge (setting myself up for heartbreak I know).
Right now I'm thinking of applying:
Land Econ Cambridge - A*AA (+interview, possibly submitted work)
Warwick economics L100 - A*AA (+TMUA)
Durham economics L100 - A*AA
+ safety option
+ safety option
Is this going to be a solid set of options to apply for or am I risking it as the top three are all super competive and picky? Also any advice for Land Economics?
FYI - I'm doing an EPQ in crypto and speculative bubbles, have written and presented on both the relationship between economic growth and education as well as should we put a price on nature, taken part in the GAIN Investment challenge, am an economics rep and am going to do an essay comp this half term. + Investment and private equity work experience this summer.
I've also done/am doing all three DOFE's, bronze silver and gold CREST, EDT Industrial Gold Cadets project, law work experience, general olympiads, schools analyst chem competition, lifeguarding and firstaid qualification, working as a lifeguard and volunteer coach and do admin at my local cycling club.

You need more economics supercurriculars (MOOCs, reading, lectures)
For econ none of your extra curriculars are relevant for your PS except fr the essay comp, econ rep, investment challenge, your presentations and maybe the work experience/epq.
I'm going to be applying for land econ as well, I would focus on the law/sustainability aspects a bit as well (you get extra PS for cambs) so make sure to do extra reading/super curriculars involved in those areas.
For Durham/Warwick, I think you'll do well, however because of Cambridge being so competitive, you want to stand out more, so stuff like a research project as well would be great
Good luck bro!

Okay!!! yes I've read a few random econ books over this year like animal spirits, thinking fast slow and now I'm reading Why Nations Fail bc its more relavent and I'm finding it really interesting. I'm lowkey really stuck on what to do for the law aspect .... I'm finding the sustanability side easier bc I've done some little bits to do with it and am really interested in development econ which ties in nicely. I'll have a look at MOOCs over the summer. Thanks
Out of interestest what colleges are you thinking of applying to and what about written work ... I'm not sure whether to go open application or pick one and then whether do apply for one that ones that require written work?

My daughter does Land Econ and loves it. About to finish her fist year. Cambridge only cares about super curriculars that are both academic and relevant to the course. Don't therefore waist too many words on irrelevant things like DoE, lifeguard etc, unless you can somehow make them relevant to the course you are applying for.
As you are applying to Economics courses elsewhere, you PS will need to be predominantly about Economics, but you can add a few things that overlap such as regional economics, environmental economics, or perhaps the housing crisis and it's impact on the economy. Whatever you haven't been able to put in the PS you can then include in the additional Cambridge questionnaire.
Remember that safety options are not just places that you have a high chance of getting into, but they also serve as an insurance option if you get into your top choice, so they need to have lower entry requirements, maybe AAB. You need to have something to fall back on if exams don't quite go to plan.

With your profile I wouldn't consider any of those courses "aspirational", they're all sensible options. I'd recommend 4 choices along those lines then pick one a grade or two below your predicted grades for an insurance.
I wouldn't bother applying to two "safety" options, unless both of them you really like and would go to even if you didn't get into any others. You only need (and can only have) one insurance offer in the end and the point of this is to select one you are likely to get an offer for and then likely to achieve it even if you miss the grades for whichever you choose as your firm choice.
Have you considered LSE? They have a course in geography with economics which may align with your land economy interests

Okie thanks - yes I had a look at LSE's Environment and Sustainable Development with Economics BSc and it looked really good but its acceptance rate is crazy low and I'd rather go to one of the three mentioned above. Its quite annoying only having 5 options but I guess it makes you think about what you're applying to more.

I'm sure you already know this, but land economy is very different to economics - are you applying to it because of the higher acceptance rate, or out of interest for the course? Also, I'd recommend only applying to one safety as you can only pick one in the end! Have you considered bath? They do a flexible offer for 4 A-Level students

Land economy has a lower acceptance rate than economics at Cambridge

Oh my mistake! I suppose in terms of applications regardless of acceptance rate economics could be considered more intense due to the TMUA and heavy maths requirements (I think most? applicants do further maths), which can be off-putting!
