Failing 3 units but doing well in 7

[hennie141]

Hi! So I just got my trial results back, and I've done reasonably well in 7 of my units. I go to a high rank school and have been told that I'll most likely be getting a band 6 in these subjects. However I failed my 3 units worth of maths and am definitely ranked within the bottom 10 of my cohort. How badly would this affect my atar if I can do well in the other subjects? Just want to know if it would be worth spending most of my time to improve maths over other subjects or keep it rather balanced with a bit more attention to maths. Thanks!
