The multiple choice questions are pretty much all in the JKI booklet, also there are some choices for some questions that vary little, but they are looking for the exact same phrase as in the booklet.
The only thing I felt missing from the booklet is maybe a bit more on meteorology and the weather.
Also you should have some insight on Cathay's fleet, which can be found on their website.
The Compass test is pretty straight forward, tests your ability to multitask I guess. If you drive or play any first person video games that require you to be aware of your surroundings it will be cake.
There is a math section that requires you to be able to do some basic trigonometry and division of big numbers. Other than that, it's pretty straight forward.
