Getting accommodation shouldn't be a problem for you. Quite a few of the cadets lodge in air arabia's serviced apartments. There are also some serviced apartments in Ajman where a lot of alpha cadets stay. There is transportation to and fro the academy provided to them. When you go for your assessment, you can ask around.
The delays are quite long I have to admit, but they have been becoming shorter and shorter. So, they are clear signs of improvements, it's just a matter of time.
The assessment test is fairly straight forward. It's at the high school level. I suggest you do some brushing up for physics, if it's been a while since you graduated from high school.
Cheers
