First off, I would like to thank all those who have helped me calm my anxiety. So, in turn, I would like to help others like me who may be in a similar situation.
WES U.S equivalency for IGCSE is indeed a U.S high school diploma.
Regardless of where u had answered ur IGCSEs, ask the certified institution (For Edexcel: Pearson, For CIE: CIE I think) to send a new copy of ur certificate (a replacement certificate) directly to WES. For that matter, u can use the online forms they provide on their website. In my case, for Edexcel, http://qualifications.pearson.com/en/support/Services/replacement-certificates.html.
Well, directly deriving from my experiences, u will notice that there is nothing written on the WES website about their contact email. So I just submitted a ‘email us’ form on their site asking about my situation. ‘Incompatible documents requirements since I had attended an international school blah blah blah’. Select ‘others’ for what the inquiry is based on. Otherwise, be prepared to be given multiple nonsensical answers. Anyhoo, after I had informed them about my situation, they changed the requirements on my WES portal.
Afterwards, I filled in the Pearson forms. For the ‘additional information’ field on the ‘qualifications details’ page, I filled in my UNIQUE CANDIDATE IDENTIFIER as I have read on some sites that sometimes they do not have ur report or sth of the sort. So I did that to be sure. And on the ‘additional information’ field on the ‘Delivery details’ page, I filled in my WES reference number. Input the address respective to the delivery method u choose. In my case, I chose the courier method. Rest assured, Pearson knows how to send to WES so u need not inform them about the seals and formalities for WES.
I chose courier so I can track and inform WES immediately once they received my package to avoid delays. It takes about 2-3 business days for them to review and update ur portal. After 3 days I found out that it still has not been updated so I informed them again who immediately updated my portal from ‘documents received-review in progress’ to ‘evaluation in progress’. Just the following day, I noticed that the evaluation date has disappeared. Do not worry, it means that ur evaluation is going to be done soon. It took 5 business days for my evaluation to be completed.
Overall, I realized reading online makes things more complicated. WES finishes its job on time. Do not believe the accusations or complaints like I did. It will only stress u out more hahaha. Oh and be polite when making an inquiry. I think that is always what caused my evaluation to be finished swiftly.
