i got 5 sups in edutest, all A's and one B (for technology) for my school report Semester 1 and my previous schools report was really solid too. Other than this one leadership opportunity called JRC, I didn't really participate in many club activities (mainly bc my school was so far away) but my extracurriculars from last year were really good (public speaking, leadership, softball team, maths olympiad, dux and more). I also got like 1st in course math Sem 1 and 3 other Academic Achievement Awards (Eng, Sci, History) which I submitted in my application. All top triangles in NAPLAN too for this year.
Actually, I initially got an unsuccessful letter from baulko but a shortlist letter from JR when results came out (approx Sept 20th i think) which I was quite disappointed about but mid November an office admin from Baulko called my mum to inform her that I had gotten an interview.
The interview is kind of a formality i guess, they just want to get to know you a bit more. The questions were like "Why do you want to come to BHHS", "Do you have friends here", "Your current school is smart but the kids at Baulko are on steroids, how do you think you will cope with maybe not being near the top of Baulko like you were at your previous school" (yes he said that word for word), "Your sibling attends this school and a lot of the times, you may feel like you don't want to go to the same school as her or you might compare yourself to her what do you think you will do about that". The principal already has the letter of acceptance on his desk he just has to pick it up and sign it once the interview is over and thankfully, i did get in.
That was my experience with the whole edutest thing I hope it helped
(Also this is just extra info but sitting the edutest itself costs 300 dollars per year and each practice test with 4 tests and 20 questions in each comes to 60 dollars so the whole thing is extremely overpriced)
