Chances of getting into U of Minn PSEO

I was thinking of enrolling in Minnesota’s PSEO course in my junior year but I don’t know how good my chances are. This is what I had freshman year:
Pre-calc:A
Physics:A
Ap Human Geography: A
Spanish 1:A
Intro to Engineering and Design:A
Honors English 9:A
Gym and other elective class: A
GPA: 4.0 unweighted
And Projected Sophomore Year:
APUSH:A
CIS Calc: b+ or -a (b+ College grade)
Honors Chem: A
Honors English 10: A
Principles of Engineering: A
Gym and health: A
Spanish 2: A
Unweighted GPA: Around 3.9
I haven’t taken the ACT and I heard that it isn’t that important, but is that true? Also, do they take anything else into consideration as well?
