the question:
how do you get from UIC (UIC/Halsted) to Northwestern (Noyes) via CTA?

the answers:
hop an inbound Blue Line train and get off at LaSalle, walk a block north, get on Purple Line LaSalle, ride til Noyes. (fare: $2.00)

take inbound Blue Line and get off at Clark/Lake, walk upstairs and transfer for free to Purple Line, take a largely unnecessary tour of the Loop and eventually get off at Noyes. (fare: $1.75)

what the RTA says:
get on an OUTBOUND Blue Line train from an imaginary stop located at the corner of Archer and Wallace (southwest of Chinatown), get off at another fictitious stop in the opposite direction of travel located at the corner of Adams and Clark, transfer to Purple Line at nonexistent station, get off at mythical stop at Elgin and Chicago which puts you in a completely different town over ten miles southwest of Northwestern. (fare: 6,274,638.52 Swedish Rupees)

nice.
