Treynor Black Model - Calculating the weights in optimal portfolio towards, noticed, question, material

IAmNeil

Hi there,
I noticed that calculating the exact weight of Active Portfolio A in the Optimal Portfolio P is not addressed in Schweser material.
Will this calculation be a likely question or is it safe to ignore the exact calculation.
I am leaning towards just understanding the nuances of the concept?
Your opinions are much appreciated.

Best of luck to you all in your forthcoming exams.
