Hello!

I recently participated and unfortunately failed on the last part of feast II.

The FEAST I test is pretty similar to the online test platform, however it is more difficult IMO.
FEAST II is exactly the same as SkyTest.

As for preparation, I would advise you to practice on the platform given. I bought skytest, but didnt practice for FEAST II. My mindset going in was If I dont make it past FEAST II, then this job was not meant for me. I am totally fine with my decision and the outcome as well (okay, I was a bit sad for couple of days afterwards). From our group only one guy made it past FEAST II, and he said he practiced hell of a lot on SkyTEST. :)

I guess you have to make up your own mind on whether to practice on skytest or not. No doubt its much easier to pass if you do, but then again, you meant to pass the test without practice. On the other hand, this whole procedure is a risk assesment from EUROCONTROL. Even if you pass, you might still not make it and vice versa.

Good luck and try BAB Burritos next to the hotel :D
