choosing how to set up a math course

 My child is going to switch to KA to complete Pre-calculus this year.  She has started with another curriculum which was  not working for her.  How do I plug her in and get her started in a precalculus course with KA?  I have found that some of the curriculum she was doing is in Algebra 2, and some in precalc and trig. Currently she is doing an Algebra 2 mission in KA, but I am not sure that will get her pre-calc completed by the end of this year.  Can you give me some guidance?
