I don't know where to start?

I'm turning 19 on 2/7 this year and i want to study (next year probably), well, something lol.

My idea is to do mature age TEE next year and then do midwifery after that (how original, eh! hehe). The thing is, would I even be old enough to do mature age TEE next year? Some sites say you need to be at least 20 and others say you need to be 19, so I am tres confused.

This is only applicable in West Aus btw so I don't know if anyone can give me a clear answer? Is there a different way for me to get into uni besides mature age TEE? I only did up to year 10 in high school.

Thanks <333
