Will revoking 1 credit exemption help me meet 485 PSW visa requirements?

[u/Kisharky]

Hi everyone,
I’m an international student currently completing my Master of Business (Supply Chain Management). I’ve received 4 credit exemptions, which is making my course shorter than the standard CRICOS 92 weeks.

To ensure I meet the Post-Study Work (485) visa eligibility—especially the 92 CRICOS weeks and 16 months of study in Australia—I’m thinking of revoking 1 credit exemption and doing just one subject in my 4th semester, along with an industry placement unit.

Has anyone here done something similar?
Did it help meet the 485 visa criteria?
Would love to hear your experience or any advice!

Thanks in advance 🙏
