That's correct. Forget about learning the majority of information. The airlaw exam is quite poorly written in English, many questions are 'double negative' in intent. It's best to use the tried and true way of passing by following the guide given to you by Korean Air. Follow the program using the notes provided by Kal, study it every night for a week and you will pass. It's only 20 questions, probably 90% of them you will have in the provided notes.
