For example, a course where according to the University website the typical offer is ABB - if it still has places in clearing does this mean they might take you with ABC? Would you just ring up and ask and they'd say yes or no there and then? How far would they bend the requirements to fill places....ACC? ABD? I know there must be many variables but would be interested to gear of any experiences. DS is virtually assured A or A* in the subject he wants to do but the other two are a bit less secure.
I'm thinking ahead as he is only just going into A2 year.
