You are two grade levels ahead in math.
You are in the hardest version of algebra 2.
How well are you doing in the hardest version of algebra 2?
How difficult is the hardest version of algebra 2 for you?
The first two points suggest that you should be able to handle the hardest version of precalculus offered by your high school, unless the answers to the last two questions are that you are finding the hardest version of algebra 2 difficult and you are not doing that well in it.
