Substitute Teaching?

[quasarvs]

Hey All,

I'm waiting on those final credits to transfer, and my plan was to just study a couple months and pass a few tests for my teachers certification. However the cost is astronomical to what I thought it would be. 4k$ on average is what I was discovering after a little research.
Unfortunately, I had not reckoned on that, so I started looking at all my options. My dream isn't to be a teacher actually that was my backup plan, so I was hoping to just sort-of get the certification in tow.
Anyway, I'm looking into substitute teaching to earn extra income in addition to my somewhat irregular income, and put it towards the certification.
Does anyone have experience with substitute teaching? Particularly, in smaller, (population-wise) schools?
One of my TESC professors said substitutes usually get the worst experiences and he encouraged me to go on and get a masters, either way I'll need to save up.

Any thoughts?
