As a rule of thumb, skill levels in MgT ae the equivalent to one less than those in CT. so, the basic skill in MgT is 0, while in CT is 1, and a Doctor (and so we can assume any university career licenciate) is skill 2+ in MgT, while 3+ in CT.
See that the example characters in CT suplement 4: Citizens of the Imperium, that are fresh from chargen, include some very high skills. There are two Scientists with computer 8 (one with no other skills, the other one with Admin 1 as the only other one), and some Boureaucrats with skill levels 6-7 (again, with little or no other skills). Even one of them has Admin 6 and Liaison 6 (but, again, no other skills).
So, if what I said in the first paragraph is true, those characters would be the equivalent to characters with skill levels 5-7 in MgT, fresh from chargen...
As said, those are quite specialied characters, usually with little more skills (if any at all)
