I recently did VCE Specialist Maths, Maths Methods & Physics thru
distance education Victoria. At my lesiure.
This is a cheap way of bringing education skills up to date. I did this to help my high school kids...but after all this they didn't want my help...all help given by me ends in tears!
If I could do it anyone can do it.....With the proviso that you need to be reasonably switched on to get a good score for Specialist Maths. I found it's student drop out rate was extremely high.
Other subjects are very educational & quite passable by most people.
