I got told to try again after 12 months idk what to do

Hey so im in grade 12 right now and i applied for A full time infantry role 3 weeks ago, i just did my psych test today, and because of my inconsistent job record the psychologist told me to try again in 12 months. she was super nice about it and told me that she would normally tell people to try again in a few years, but for me she said “i can see youre trying to improve as well” and so she gave me 12 months.

Ive really wanted to join the army since i was a kid and thats the only job i really wanted growing up, can anyone help as to how i can improve my record and get a better chance on getting accepted into the ADF? I asked my case manager and she said to complete grade 12 and get more job experience but I want an in depth answer into how i can really improve myself. Im not letting go of my dream job this easily and ‘d really appreciate if someone could help me with this
