I didn't to great but didn't do extremely bad in my hsc. Unfortunately due to the subjects I was doing it lowered my ATAR a lot and I was way under the required ATAR to get into teaching.
If it wasn't for principals recommendation I would not have got in.
Now I have just finished my first year and doing a lot better in uni than I did in high school.
I do agree there are some people who do teaching who shouldnt and only choose it because they think they know what to expect as school is the only life they know and holidays etc etc.
Teaching is something you do need to be committed to.
After doing my first prac I realised there are some selfish and bad parents out there and the kids in k-2 can quite often fall so far behind and/or need to be taught skills that their parents should teach them.
I didn't mind history during school but was not overly wrapped in it.
I think it is something that with age we come more interested and willing to learn.
