Secondary for me <3 I love my little brats. They make me want to murder things but I always end up bawling when I leave them.
I thought about going into primary teaching but I worked in a primary school for work experience and I had to chase a nursery kid around telling him to put his pants back on. Was not fun. Also snotty noses ew.
I don't know if a level 6 qualification would be enough to be a full time teacher to be honest. I'm pretty sure most PGCE/PGDE/School Direct/etc. courses require you to have a full blown degree. Maybe you could be a part timer or an assistant with that level but I don't know you'd have to look into it.
He's doing fine now, he's on the top-up and he's prepping for next year. He's got an interview Monday for a work placement he's doing as part of his course. Plus he's living with my next year so if all goes tits up he could probably jump onto the course at my uni to finish off his degree.
