One of the frequent reasons why candidates for cadet programmes fail is that they
1) apply too early
2) apply because their friends applied at the same time
3) apply before their English is good enough because they think they can improve it in the 2-4 week period between their aptitude test and their HR interview.
The reason is very much due to patterns of social behaviour which have developed from exposure to a highly commercialised and test focused learning environment. My advice is don't wait until you have attended an aptitude test before starting an Aviation English course with Aviation English Asia Ltd. Similarly, don't think of technical knowledge, eg aviation theory as being separate from English proficiency. And don't get bogged down in technical knowledge that won't be relevant for the foreseeable future if you can't even use present simple correctly.
Aviation English Asia Ltd courses can guide you through every stage of an application process, and you will improve your English as you improve your knowledge. Even candidates who have relatively strong English can improve their English, and even candidates who are relatively strong with their knowledge of aviation theory can improve their technical knowledge. We can help you regardless of the stage in your application procedure, because AEA teachers are the best of both disciplines. We are well aware of the profile of successful candidates, so trust our judgement. Aviation English Asia Ltd provide the right thing at the right time.
