Taking Precalc Honors without taking Alg 2

Hi the honors track as my school is:
Alg 2
Geometry
Precalc
AP Calc AB/BC
Multi Variable
Differential Equations

I am taking Precalc as a sophomore so I am a year ahead of most honor students.

Going into freshman year, I took an exam to test into geometry. I somehow passed without taking Algebra 2 in 8th grade. This past year, I aced geometry Honors (which was mostly a class with sophomores) having a 99% both semesters.

However, only algebra 1 was needed in that class. I am worried that next year for Precalc, I’ll have trouble being weaker on Algebra 2 topics.

How much will I be affected by not taking Algebra 2?

What topics of Algebra 2 are most important to cover over the summer for Precalc?
