if u have problems accessing ur old school, u can meet up with any pegawai kumpulan A in any government office and get ur certificates certified. they're usually officers who hold a commanding post, and usually holds a degree. just find any human resource managers, and they can tell u who can certify ur certs.

if u're really not sure, go find a solicitor. they can certify ur certificates (u can even use them as a legal binding, if need be), for a cost of about RM5 to RM10 per copy.
