My school is doing its best to fail us

They also proposed to get rid of skill level sets. RIDICULOUS. For context set 1 is the top set and set 5 is the bottom set.
The higher sets learn different things, such as the higher paper rather than foundation, they also learn at different speeds and comprehension levels to the bottom sets. This makes everyone's education worse as nobody will get the support that they need. Higher sets will be held back, lower sets wont be getting support, a majority of people wont get the proper support needed. My school seemingly wants to see us fail. It disgusts me.

There are multiple schools with that name. The one in Barnet is rated as outstanding by Ofsted, but there's one in Dorset that has a low rating.
There should be ways to complain. Some of the things you described aren't major issues, but the English lessons are a concern.

My School, Queen Elizabeth's School. Is doing its absolute best to ruin our education. Since 1 term in through year 10 (I am in year 11 now) the school has stopped giving us any English Language Lessons, and even in Literature, we are not getting taught how to answer any questions, no practice questions, no essays, nothing. We are getting thrown into the deep end blindfolded in our exams. Many of us are relying on external tutoring to provide the baseline education. My school, last night at a parents meeting, announced that they would change the lesson structure to be 4 lessons a day with 1 hour 15 minute long lessons. This is ridiculous. Lessons have been 1 hour long across the nation for decades if not centuries. All the lessons have been designed around a 1 hour long lesson making them obsolete. Also many people can barely concentrate for 1 hour let alone 1.25 hours!
It also means, to have the same amount of lessons we need one whole extra week worth of lessons to have the same amount as we do currently. Also, most subjects have all the content planned to fit in a specific amount of lessons which will be significantly reduced after this change. They also force us to do line ups before school in most weather conditions until every single person in your tutor group has immaculate uniform. This doesn't even fix the uniform problem. People Unfix it as soon as they get inside.
These, among many other things are examples of how my school is trying to ruin our education and set us up for failure. Our school got a needs improvement in its latest Ofsted report and it isn't looking good for the next one.

+1, QE has been historically highly regarded, so your complaints come as a shock to someone who applied there in my own 11+. Do you have any official communication about these changes? Could it be that you're misunderstanding them, as the concensus is that QE is a great school?
While tutoring is beneficial to your progress, it's definitely not necessary now with resources all over YouTube, websites, and even GPT. On a side note, make sure you're using those effectively, otherwise you'll struggle in your A-Levels and further study where self motivation and guided study are the norm.

Complain to them or move schools

I am going to try and complain to my local MPs as well as the school as the last time that I complained to my school about something, they just didn't care and refused to listen to what I said. The learning trust (initio) also doesn't care, and both the trust and my school are in shambles due to poor management and staffing issues because the school is so poorly run, staff don't want to stay. When I get time, I am going to complain but unfortunately I don't think much will come of it. I can't move schools/ apply to a different 6th form as I don't have a way of getting there and I don't want to leave my friends as I don't think that my education has been compromised enough to leave my friends. Anyway, the school changes the timetable format on average 1-2 times a year. (They are incompetent)

Lessons have not always been an hour - it's a pretty recent thing.

We had 35/40 minutes lessons when I was at school and one school where I taught had 50 minute lessons.

What did Governors say when you/your parents complained?

Yeah, we had 45 min lessons and 90 for doubles and that was 30 years back.

As above lesson timings are not standardised and determined per school. One school I went to had 1 hour lessons 4 days a week and 45 minute lessons 1 day a week (which was an extended day, so they snuck in an "extra" lesson that way, but all the lessons were slightly shorter to help facilitate that and the additional break required for the longer day).
Also if you find concentrating for 1 hour a struggle...well unfortunate that's something you will need to work on for educational and other purposes now and in the future. It's quite likely you'll have double lessons (which were 2 hours or 90 minutes on Wednesdays at my 6th form) in 6th form, and at uni it's not uncommon to have 2 hour sessions for lectures, and longer for labs etc. I once had a triple (3 hour) lecture for a given module which was basically the entirety of that module teaching each week (with then a 1 hr seminar later in the week). Plus once you move into the workforce well...yes you're going to have to work for several consecutive hours, not infrequently on the same thing. And unfortunately you WILL probably end up with some godawful 2-3 hour meeting in your diary every couple months (or more often if you're more senior!) for something or another (even worse when its mandatory in person!!).
The bigger concern is the (apparent) dropping of English teaching at your school. Where has this gone? What is being done in the time periods this was taught before? Have they actually removed this teaching or just changed the format/name of it...? The other bits are small fry and mostly neither here nor there, and detract from what should be your central focus - which is if you are not being taught in one of your compulsory subjects. That should be your focal point.

I emailed the board of trustees at initio. they never replied. the school itself talked to me and refused to actually respond to any of my points. The 75 min lesson is unsuitable for us for reasons including:
we would lose 195 lessons in an academic year. the extra 15 mins does not make up for that. The added lesson time is negligible. It would be a lot harder to fit the course content into less lessons, the added 15 minutes cannot help that.
Most people's attention span for a lesson cannot extend that long, doing the same subject for 75 minutes adds to the mental fatigue of school and exams. The main point is the lost lesson time with the proposed new timetable. Our school also has many students with learning difficulties such as ADHD, among others. The school does not have the staff to support them, and they will suffer the most with these longer lessons. The school can't provide support with the 2 members of SEND staff we have for an at least 800 pupil school.

they have replaced teaching English language which equates to a whole GCSE, and just done more English Literature in its place, whilst not even teaching that effectively.
