Do universities accept A levels over 3 years?

DS has ASD and a statement of SEN. He missed the offer to study Physics, scoring unexpectedly a B instead of predicted A*. So he started learning Maths, Further Maths and German as planned. However the school doesn't think he should do a forth subject - which was supposed to be Physics, so now DS is left with potential 3 AS and there is a chance that score very briliantly in the German A2. So DS will be retaking Phisics GCSE and trying to do 4 AS and 3 A2 including Physics over 3 years.

How would universities look at this?
Is 3 years a worse option that 3 AS and 3 A2, with potentially one A2 not very good?

What options if DS gets good Maths grades but say a D in Germamn at AS/A2?

Just want to clarify what I mean by 3 years. I mean DS droping German after AS in year 12 and starting Physics AS in year 13 and completing A2 in year 14 as it were. I know the curriculum will change and it will be one final A2 exam, so in this case DS would take it a year after his other A levels.

So, according to this plan he would have AS German, Maths Further Maths in year 12, A level Maths and Further Maths in year 13, and A level Physics a year later.

So how will this be looked at for an Engineering or Maths degree?
