bahaha they called my mum and then send an email, as well as a document of confirmation (basically confirming if you want to attend sgg). i did my selection process during lockdown– but they confirmed, by phone, the day after my interview (this varies tho)
bahah sgg is alright; the school definitely has a competitive atmosphere, where the majority study a high amount of hrs and attend matrix. dw about the interview– it is not necessarily the make or break! regardless, good luck and dm me if you have any questions :)
