Do I have a realistic shot?

Hi guys I'm a 14-year-old student interested in math. I've done some competitions in Year 9 (13 yo) and the results are: AMC8: 18 UKMT IMC: 107 UKMT SMC: 85 I know these aren't amazing scores, but I'm trying to improve and I'm wondering if bmo1 qualification is realisitc. If so, what should i start doing and when will i reach it? If you don't think it's realistic, please just say no and don't call me dumb... I know lots of you guys here are super good at math Thanks!
