Usually it takes between 6 to 8 weeks from the date when the window for applying for certified copies is kept open. But it would not be possible to give a definitive period with which you will receive your copies. It could sometimes happen earlier than the period mentioned by institute in the website, as it has happened in your friend's case. Wait for another two to three weeks and if you don't receive it, call up institute.
