Funny, I was recently removed from a group in Pakistan for guiding regarding this matter.
Anyways, I completed my O and A levels. Got their equivalences made. Enquired how to send my O and A level certificates to WES. Through Cambridge. It was costly and time consuming. So I got my equivalences attested along with their photocopies attested too. Got these photocopies sealed in an envelope and stamped on the seal. Sent it to WES via DHL with IBCC’s address on it.

About the Bachelors and Masters. You need to get both of the degrees and final transcripts attested by HEC along with the attestation of the photocopies of these documents. Get the photocopies sealed, signed and stamp from HEC in one envelope. Send it to WES via DHL with your address in the senders portion.
In Shaa Allah there will be no issue in your evaluation from WES. I even took pictures of the envelopes to help others get an idea how it should look like.
Remember to enter all of these credentials during your online application at WES so that they will evaluate each of your certificate as per the entered credential step by step.
O levels - equivalence certificate
A levels - equivalence certificate
Bachelors - final transcript and degree
Master - final transcript and degree
All attested photocopies. Two envelopes.
Good Luck!
