Hello, I recently got the waec scratch card and it's a quite easy process.
First there are 2 categories for the waec school certificate and the GCE certificate holders.
For school cert:
You would need 2 envelopes, about 3 passport photographs, original waec result, scratch card, photocopy and an affidavit. The affidavit should contain the candidate name, exam number, year of exam, subjects passed, credit obtained, etc.
The gce cert holder would need 2 envelopes, about 3 passports, letter of attestation from an imam/pastor, the waec certificate and photocopy, affidavit and scratch card.

This is done only at the yaba office.
You would need to pay for courier or postal service. Postal service as at November 2018 was 1800. Then courier varied from 8500-10k. I used the one of 8500,aramex.

Please bear in mind that waec no longer produces scratch cards with silver panel so I had to buy the paper type. I have not received a report but a friend who did same thing, sent me a screenshot that her waec scratch card was not received by WES. I would advise you buy the old type of scratch card. [/quote]

I have the same issue. I stay in Benin City, do I have to travel to Lagos to get this done?
