USA first year undergraduate attempting to apply to london School of Economics & Political Science

I am currently an undergrad first-year student in the USA. I attend the University of MA Amherst – a state school in MA. I am trying to see if I even meet the entry requirements to apply to LSE. I am thinking of applying to one of their International relations degree programs. My stats are the following:
AP scores:

AP US History- 4
AP World History- 5
AP Comparative Government- 4
AP Calc AB- 4
High school GPA (weighted; my highschool weirdly does not calculate our unweighted GPA) -3.98
current college GPA (totally an estimate b/c semester hasn’t even ended yet): ~3.8
Not that it matters but my SAT was a 1460/1600.

I know that we are supposed to send in 5 ap exams with all scores of 5, but I was wondering if there are different entry requirements for students already in college.

Yes, completion of a year in a US college means the APs are less important - but you do need to report all the scores.

If you go back to the page on the LSE website that talks about “Undergraduate Entry Requirements” on the USA page, and keep scrolling past the parts that don’t apply to you, you will come to the part that does: “Students Applying From An American University”.
