Regarding O & A levels:
What I have read from this forum....someone shared their experience that he just got the equivalence made for both and sent that,along with photocopies of O/A levels result to WES and his status read application in process so yay I'm done.
I messaged him to ask if he got his ECA but got to replies yet.
On the other hand, I bugged WES ALOT with it. Kept emailing them because I myself have done O and A levels.
What they have to say is
"Please visit the link below for document requirement for Cambridge International Examinations/British Council
http://www.wes.org/required/UKExamBodies.html"
Meaning, we need to get the certifying statement for our O, A'levels from Cambridge, which is a 4 weeks procedure and 33 pounds for each statement, O levels and A levels separately. Cambridge sends these statements directly to WES.
Now this is confusing, as WES requires something else but approved the equivalence for O and A levels for some1..??
If you want to be on the safe side, go with WES instructions that I have stated above i.e the certifying statement for both to be sent to them by Cambridge.
But you will still be needing the equivalence for the HEC attestation of your bachelors degree.
