Non-degree tertiary means that it is a certificate but not a university degree.
You are higher than form 7 but no yet getting a university degree e.g. 副學士
如香港中五畢業, 有考 HKCEE 再加有 Professional Diploma 合資格嗎 ??
Are you form 7 finishing student?
I think not 合資格. but you can try because sometimes if there isn't any qualified people applying for the position-the company may hire the people even though you are not 合資格.
