I started riding when I was five, didn’t do my first event until I was 12 when I got my first horse! It can take year but enjoy the progress in your riding to get you there and have fun. It may take years it may only take a few months but the important part is not to rush and to have fun
Slow down! You've only just started jumping. You're flying through everything. Give it time. It's easier to learn to do things right the first time around, than have to unlearn bad habits and mistakes.
