Dear respected,
I have PhD degree in Computer engineering, and I have written over 100 engineering documents and reports.
I am the author of 2 books and editor of an International Journal.
I am well-motivated, reliable person, with more than 15 years writing and teaching experience. My approach is “dedicate to the client” and I am not gained with bunch of projects. To check my publishing sample – open the attached file, or just google “Zoran Gacovski”.
Regarding your question: the synonym for "fail on exam" could be "fall" or "decline".
With best regards,
Dr. Zoran Gacovski
