Hello,
i bought 3 books about how to solve cases and worked through them. In addition, I have done over 30 cases and spent 4 hours with a coach. Nevertheless, I am not getting any further in my learning success. I am a bit frustrated and do not know how to approach the whole thing. Somehow it is never perfect, or I struggle with small details. That's why I'm asking myself, how do you become advanced or very good in casing? Does anyone has some recommendations?
