I'm hoping for some advice please 
DH has decided he wants a career change from management accountant to primary school teacher. We've established that he'll need to do science GCSE as he only got a grade D when he took it first time around (many moons ago and before he realised he actually needed to work at school!). He doesn't have any A-levels or a degree. He's got an advanced GNVQ in business studies and AAT which is equivalent to NVQ level 4. He wants to do a B.Ed at our local university, starting in September. Does he need to get A-levels as well, or can he do an undergraduate degree with just the GCSEs?
Also, what's the best way to go about getting work experience?
Thanks in advance!
