Am I crazy for considering doing A Levels again in same subjects with A*/A??

I have struggled to get a job since graduating University and only ended up doing some private tutoring after failed teacher training applications.
I managed to get on one course but struggled to match the fitness to teach requirements due to what was at the time undiagnosed autism and the course didn't really suit me due to essay requirements.
I want to do teacher training but I had a mental breakdown and have been out of work for 3 years(apart from the last few months where I unsuccessfully tried private tutoring again). If I just aim for QTS will there be little essays?
My aim is to retake and update my A Levels in Mathematics( got A*), Further Mathematics(got A*) and Physics(got A) to give me more up to date knowledge since A Level courses have changed considerably and that's making private tutoring hard. Then, I could do teacher training. I want to teach A Level mainly not so much GCSE.

As others have said, you definitely don't need to redo your A Levels.
You need to have not dropped out of teacher training.
If you aren't able to have another go at teacher training, then you aren't going to become a teacher. You're limited to being a tutor.

Have you thought about working as a TA for a year to get some classroom experience?
No-one just teaches A level even in a sixth form college.

Your A level grades were clearly not the reason you previously dropped out of teacher training so what do you think retaking them will actually achieve? Nothing meaningful, and this will not instantly fix your other issues which are clearly still holding you back.
Do you now have a formal diagnosis for autism, and are you receiving help with your mental health?

What would be better redoing A Levels(maths, Further Maths and Physics) or Access to Science Diploma(mathematics, physics, biology and chemistry) for maths teaching?

Teacher assistant roles for just Maths seem rare.

You will be assigned maths support with your qualifications.

What about the Universal Credit situation? I currently get both LCWRA and PIP so I should be eligible to study on these benefits. I found a Teaching Assistant role that's temporary till July 2025 but if I got the role I might be back on Universal Credit in July 2025 without LCWRA.
Problem I have is the teaching assistant job says experience of working in classroom environment essential. This seems to be why it's so hard to get a job these days they all demand experience.
