College student credit journey (maybe i can help you)

So I am currently a JR in college (for another 4 days lol) and wanted to share my credit history with no parental help from AU or cosigning.
1/2023 (was in community college part time while working at the time), discover it student cash rewards, $500 limit was raised to 1300 at some point
7/2023, C1 savor, was the savor one at the time $4000 limit
5/2024, apple card (imo, worth it if you buy like 1 apple product a year) and no AF, so it doesnt hurt to have, $3000 limit
5/2025, United explorer $7200 limit (my main card these days).
happily open to questions, suggestions or whatnot
