dont do it online ..
if u are only going to attest from hec .. then u only need the original degree .. if u want to attest the photocopy of degree u will need original degree.. if u are going to attest the provisional degree or transcript .. u need a letter from ur univ stating u are real and u need its verification .. or something like this .. only to convince them ..
dont do it online . if u do it online it will take 2 months to get the number and u will still be required to go there .. for safety ... at least ..
just reach the hec building sharp at morning ... like 7-8 am .. as after 11 o clock they stop giving tickets .. only those who came till 11 o clock are allowed to register ..
most of ur time will be spent in filling the online form at the hec lab ..
so i would strongly advice to fill the form online from ur home and dont get any appointment .. then go to hec and just get a print .. u will get earlier print and will be farag at 12 o clock... else u will get farag at 5 o clock ..
if u want to verify from foreign office .. u need to verifiy ur metric fsc from respective board .. then ibcc .. only then those wil be verified by fbise ..
all in all its a big khwari
