Quality Courses in Business, Marketing, IT, Languages (including English) and Other Fields
One of the great things about the online revolution is that you can learn about pretty much anything in the comfort of your own home, at your own pace. There are now many great websites offering courses long and short in many areas of study.
Check out Udemy, for example. This massive site offers numerous courses by respected experts in various fields. Some of them come with certification, too! That's handy if you want to impress a prospective employer.
You may have a particular interest in languages. In that case have a look at eTeacher.
I know that many people in Sydney were born overseas and grew up learning the language of a different country. If you are in this situation and wish to improve your English skills Rocket Languages could be ideal for you.
