I'm not really sure but I think you may have to come here to apply. They would usually email you in advance when the orientation is so you can prepare. It might take you 1 to 2 months to finish all tests depending on how fast results are given.
To put you into perspective, this year, they were only getting 36 applicants. During the orientation seminar, I think there were more than 200 (estimate) or so who attended. Could be more...
