I did a Certificate 4 Business Administration

I started it in 2009 and finished it in 2017

I tried doing the full course, passed 6 units out of 11, then passed a few more a couple of years later, did the last unit in 2017 while taking a break from my uni course for a semester. 

What I'm saying is that even if you don't pass all the units now, you can take it at your own pace too, just do what you can, it won't be a waste
