Can I qualify for AIME if I’m a chud?

so basically I’m a rising junior with minimal competion math experience…last year I got like a 37 or something like that on the AMC 10. this year I’m taking both the 12A and 12B and want to qualify.

i took like a practice exam a few weeks ago on a recent previous amc 12 and was able to get like the first 9-10 questions correct.

i was wondering what the absolute “best” way to study is(I’m in a normal accelerated math track at school for context). I can put in around 15-20 hours a week until then.
