Crystal Clear Exams
I technically started these manuals while I was studying for CAS 9 in 2017.
The CAS 9 Manual was then largely based on the notes I wrote up for myself while studying, with a good amount of refinements. Since the first publication, the manuals have morphed and changed to add more flexibility and of course information :) .
Hopefully you will find the manuals useful, and, as they are ever-evolving, if you see any opportunities for improvement, do let me know!
