saw a femboy at nust

jk. anyways, in joining instructions it's said:

d. Original SSC, HSSC (or equivalent) along with 4x photocopies of each certificate duly

attested. (Keep photocopies and scanned copies for your personal record for

subsequent use) as your original documents will be retained by Institute.

and

f. IBCC attested copies of SSC and HSSC

so for foreign qualifications who have equivalence certificates, do we just need 4 photocopies since they're already attested? or do we need to get the photocopies attested, and by whom? also for og marksheets, do we need those attested? because ibcc dont attest foreign marksheets either. thanks!!
