the reception people have nothing to do with the atc training side of the college...you mention area or aerodrome courses they will probably look at you like you had spoken in swahili (sp). They deal with the more business side like visitors and meetings etc.
General courses you study are Meteorology, Aviation Law, Human Factors, Navigation and aircraft characteristics. best to just relax before you get own there the only thing that will help to read up on is Nav. When i was there 2 years ago they sent out a learning package for Nav to read before you go down, this is helpful. Not sure if they do that anymore.
