Your other posts indicate you are a CA HS freshman and are interested in CA schools especially the UC’s. The Cal states and UC’s Carnot consider race or ethnicity in their admission decisions. Your SES ( socioeconomic status) and first generation is a consideration however.
If you want an extra tip with your URM status, then you would need to target private colleges that would want your diversity.
Regarding classes, you would want to maximum the a-g courses required for the UC’s and Cal states which would also fulfill all the college requirements across the US.
4 years Math up to Calculus if possible
4 years Science including Biology/Chemistry and Physics
3-4 years of a Foreign language
2-3 years of History (US, World, European and Government)
1 year of Visual Performing Arts (Art, Music, Choir, Band etc…)
1 year of an Elective such as Psychology, Economics.
Does your HS offer PTLW courses in some of the Engineering disciplines? These might be an option.
Also does your HS have a Robotics club?
You have been given plenty of suggestions in the above posts so best of luck and HS is a great time to explore all options.
