Is my understanding correct - you have completed Year 10 at school?
If yes, then you will need to carefully check which education providers will accept an application from someone with only Year 10 and under what circumstances. It is my understanding that most Vocational Education providers require at least Year 11, and Universities require Year 12. A mature person with many years work experience, for example may be accepted, but a young school leaver may not.
As an independent Education Agent, I conduct research into which courses and education providers may suit your requirements. Please feel free to contact me if you would like further information.
