i suggest u should opt for sec 5. going for cert like NITEC or
NTC-3 cert r kinda not recognise in my view.
at least if u got gce o level cert, it can enable u more option to
choose ur career path next time like:
if u do well, u can go to poly; while if u do badly, u still got
choice to go ite but a higher cert like ITC, CBS or NTC-2. these
cert do enable u to poly next time.
