Zone 2 u are right about the new students, but to my understanding and moreover hope (Cos I need to succeed one for my admission in the school) it wouldn't be an Aviation English Test but an English Language Proficiency Test so as to assure that the student has a little above average understanding/Comunnication skill.....
In a way its good so that if in case I or anyone would get a CPL and is unable to communicate or understand properly ,wuts the use.......
