EVA Calculations

Apologies in advance if I have started a new string for an already existing topic.

I hope to sit for my P5 exams in June 2017 but struggling to grasp the content of the subject matter, specially with EVA. I read the student accounting articles, the Kaplan text and attempted the examples and exercises on my own. However, the existence of 2 approaches to derive the NOPAT still confuse me.

Please be kind enough to suggest past paper questions that can be attempted and any other means and methods I can follow to clear this confusion.

Thank you. 🙁
