Help please, parsing these.....
48a. Satisfy, for example, university - having learned about it. (7) - ASSUAGE (Satisfy)
It looks like:- for example = EG, + U(niversity) + It = SA (Sex appeal), but that leaves me with another SA unparsed, so I've gone wrong somewhere.
7d. Top bloke, heartless sort, extremely contented (8) - HAPPIEST would fit the def. (Contented), but other than - ST for 'heartless sort', I'm at a loss.
39d. "Without class" describes individual? That's clear (9) - EXONERATE (Clear)
