Do I stand a chance at Oxbridge?

I dont think I stand a chance but some posts make me so confused.I am currently in Year 12 and my GCSEs were a chaos, I got 66666777778 and in A-Levels, im doing Maths, Physics and Compsci and I want to do engineering or Compsci and I dont know if I should apply. I do have a extenuating circumstance. Can you guys give me a REALISTIC opinion if i should apply to Oxbridge ?

Your biggest issue with Cambridge is your lack of Further Maths. Have you checked the requirements for those two subjects at both universities?

Here are a few tips. https://expertonlineeducation.com/blogs/f/tips-to-get-into-oxbridge-a-guide-to-success

A quick glance at the Cambridge Engineering undergraduate page tells you that Further Maths is highly recommended, and in fact 96% of recent successful applicants took this qualification. In addition, 5 colleges actually require this subject, and 1 college may actually ask you to sit STEP II.
I would suggest you check out the Oxford requirements for yourself, but I suspect you'd be significantly disadvantaged in a Cambridge application.
ETA: Just spotted you asked about CompSci too - that is even more specific about requiring FM if your school offers it!

For compsci:
Cambridge will certainly reject you for lack of further maths at A-level. Oxford may not reject you immediately, but the admissions statistics tell pretty much the same story as at Cambridge. Your chances are very slim unless you perform extremely well on the MAT and demonstrate significant mathematical ability by independently learning further maths content.
Engineering:
I don't know as much about these courses, but I would imagine that you would have a better shot at Cambridge than Oxford since your GCSEs will likely be a less competitive element of your application (and people seem to think Cambridge is more lenient about GCSEs).

You will find yourself at a great disadvantage in admissions assessments if you don’t do a lot of additional maths. It’s not about the further maths content (which won’t be assessed), but more about the fact that you’re going up against people who quite literally do at least double the amount of maths (maybe more - the further maths at A level is a lot more rigorous and difficult than maths).
Is there any way you can do some additional maths on top of your A levels? Is there any way your school can help?

I’ll be perfectly honest, I don’t think the GCSE thing is true anymore. I don’t think there’s much discrepancy between the way Oxford and Cambridge consider GCSEs - Oxford are just more transparent about it. (But this is just my personal view and I may be biased because of the college I applied to/the admissions tutors I spoke to).

My school cannot really offer me anything but I do a programme with STEM SMART by university of Cambridge and isaac physics and they offer maths sessions which are quite challenging and unique. I DONT KNOW IF THAT CAN HELP

Sign up for the double maths sessions with Stem Smart, those are super helpful and will teach you some further maths techniques!

Not going to remedy the lack of further maths.
The other thing is... A 7 at GCSE Maths. Whilst Cambridge don't formally have GCSE requirements your teachers are going to have to explain how you're going to get from a 7 to an A* at A-Level/why you have underperformed at GCSE.
