(PLEASE HELP!) How to Get Into Texas Academy of Math and Science)?

I will be entering freshman year of high school coming school year and wanted some advice before I begin.

I’m really interested in applying to TAMS, and I wanted to know what the admissions are looking for and how to get in.

I’m hoping to taking Algebra II in 9th grade (taking the Geoentry CBE after attending TAMS SMI). I’ve not always been strong at math and science, but I want to prove it in someway during high school. What are good stats, SAT scores, general grades, and clubs/extracurriculars that would boost my chances in getting into TAMS?

Thanks~
