Great name, Mr. Success.
Your SoP exhaustively covers your intended STUDY ambition but does not address the second half of the prompt (
your most outstanding non-academic achievement involving other people where you demonstrated leadership potential.) You don't need to spend so much space citing the courses you took, better to devote it to your most significant achievement i.e. application of what you learnt and want to further study.
After a year and half, I moved to the Investment Management unit of the same firm to familiarize myself with how to apply different methods of investment appraisals to a specified investment goals, Business development & Negotiation and advisory.
HOW DID YOU APPLY THE METHODS TO BUS DEVELOPMENT, INVESTMENT GOALS OR APPRAISALS, NEGOTIATION, ADVISORY (to what??)
To achieve my career as planned, I want to delve deeper into the subject Petroleum Economics to be able to help my home country Nigeria carry out independent research and analysis, value oil and gas projects, assets and companies using the petroleum finance techniques, and critically analyze those of others to help make informed and astute oil and gas investment decisions hence my decision to join the Masters program Petroleum Economics.
BREAK UP THIS SENTENCE, IT IS WAY TOO LONG.
I believe that with my strong Research and Investment Management background, studying Petroleum Economics will be a plus for my home country.
THIS IS BETTER WORDED IN THE NEXT PARAGRAPH.
I want to be an international person in Oil & Gas Industry.
DO YOU MEAN TO HAVE AN INTERNATIONAL CAREER?
IS YOUR CAREER GOAL TO BE AN ECONOMIST (do research,) FINANCE AND INVESTMENT OR IN MANAGEMENT? HOW DO YOU SEE YOURSELF CONTRIBUTING TO NIGERIA. I WOULD THINK THIS IS A KEY CRITERIA FOR OBTAINING THE SCHOLARSHIP WHICH I DID NOT READ ANYWHERE IN YOUR SOP.
