Hi I just did it in August from Lahore board
1- Make WES profile
2- Take print out of WES Academic Records Request form
3- Take 2 photocopies of your FSC/Intermediate certificate
4- Submit fee in board bank branch (If you will visit them on saturday then you need to visit HBL bank near gangaram hospital) fee is around 1500
5- On window number 17 or 16 I think (You can ask from reception that I need to do WES they will tell you exact window number from where a from will be provided by them)
6- Complete that form given by the board and attach your payment receipt with it along with photocopies of Intermediate & WES Academic Records Request form
7- Now your papers are submitted and they will send it via normal post within 2 weeks
Normally they took 2 weeks, so after 1 week do visit the room number (you can confirm the room number from person to whom you have submitted papers) where your courier will be ready for WES delivery. However I will recommend you to send it by your self, like do collect that courier envelope and send it via OCS (they will charge you around 2200)
Any confusion, please ask
Thanks,
