Hi
You'll find out whether or not you have passed the tests within the next month or so, I believe the final pass mark will be set at the end of November once everyone on your schemes will have completed their tests.
Once you find out you're successful, you'll have a week for the form. I'm on the same two streams, but there are only questions about jobs, education, references, etc, and one small mini-essay about your choice to choose EFS. As I know, this form is only for HR purposes and will also be used in the final EFS paper sift after Assessment Centre.
From there you'll have two weeks to complete the e-tray.
As for options, I suppose you have already selected whether you wish to apply for the DS section of EFS at the initial stage as I did..?
For GFS, yes, the form is the place where you'll choose which options you would like to pursue. They are HoP, DS, Science and Engineering and CD. Which were you planning to apply for?
I'm also applying for EFS and GFS (DS for both) and awaiting e-tray results. Even though I know they haven't even set the initial pass/fail marks, I can't hep but feel rejected already, haha!
