I bought the Airline Revenue management course earlier this year, unfortunately due to lack of time and as I changed the company I was working for to join a new start up I didn't have the time to explore it in details yet, and had to delay the exam , the negative side so far is that there is no sample exams on IATA Website or such to know how you would expect the exam to be ... however there is an exam after each topic / module not sure though if the final exam would be the same
