Recently diagnosed Level 1 ASD but concerned

Hi everyone, my son has just been given a diagnosis of Autism -Level 1.  We were asked if we had any questions about it but at the time said no.  I am now wondering about the Level 1 meaning.  The assessor said Level 1 would have previously been Aspergers. I actually feel he needs a lot of help from us at home and in social situations and I certainly don't believe he is capable of living independently as he has no idea how to look after himself, run a home or organise his finances.  Does anyone here know whether there is a big difference between Level 1 and 2 please?

Thank you.
