Alevel Maths

For universities, most of them do want an A in Mathematics by the end of the year because my course is Accounting and Finance, which is why I'm stressing about being able to improve my grades to an A in Maths and still keeping my grades high in other subjects that I'm doing.

I went and had a talk with 6 of my teachers today, and they all had different opinions on whether I should drop BTEC Hospitality. This got me really confused because there are so many factors I feel like I have to consider.
I could really use some advice because it's been stressing me out and Year 13 only started a few days ago.

So some background information:
The A-level subjects that I take are Math, Economics, Accounting and BTEC Hospitality. I want to study something along the lines of Accounting, Finance or Economics at university, and I'm considering going to the UK for my undergraduate studies.

Originally, I was only planning to take BTEC Hospitality in Year 12 to keep my career paths open, but I later realized I was not really interested in the subject, and I was considering dropping it, but I was halfway through the year, so I decided to just finish it and get my grades at the end of year 12. And on results day, I got an AAB (B in Math) and a Distinction in 3 of the BTEC Hospitality units. So, most teachers have said I did really well in year 12 and that if I could keep it up, I could end up with perfect grades by the end of year 13.

Now the situation is, the A-level subjects I do can be very heavy on content and I feel like adding a BTEC which has a lot of assignments every day, so that I can be on top of my work. But the reason I'm struggling with making a decision on whether to drop it is that some universities in the UK need a high number of UCAS points to be able to consider applying to their university. Even though I don't necessarily like the subject, I feel like if I kept it as a backup to keep my UCAS points high because my other subjects do not go so well, I could still apply to some of the top universities in the UK. However, since I was able to get 24 UCAS points from finishing half of the BTEC Hospitality qualification in Year 12 I thought maybe I could just drop it and focus on my three main subjects that I will actually need for universities.

I feel like this is quite a lot to understand, but I would really appreciate it if someone could guide me on what may be the best option in my case.

I'd also like to ask if a student with high UCAS points is more likely to get accepted into a good university even if their grades are not that high, but their UCAS points are high because they did 4 subjects compared to someone who only did 3 subjects. Or even if someone with 4 A-Level subjects that has done really well in them, are they more likely to get accepted into a very good university compared to a student who's done really well but in only 3 A-level subjects?
