I did both and WES GPA was much higher than ECE why there is a difference I am not sure.
But my advice is to start working on getting ECE because almost all programs ask for ECE except Rochester which asks for WES
For that you need your Diploma which shows your GPA and the year of graduation and Transcript which shows that marks or grades for each year, both need to be in sealed envelope that is stamped and signed by your school register, then sent directly to the ECE you can choose to do the expedited process which will cost an extra $80.
