Should I review my TESOL materials before I start teacing?

[alwaysstriving]

I'm soon headed to China to teach adults. First time teaching in China, first time teaching adults (before I taught kids in South Korea for a few years).

 

I took an online 120 hour TESOL course a few years back and I have forgotten much of what I learned from the course. I am of course going to briefly review my TESOL units and my other teaching materials before I start teaching in China.

 

Since I am working for a large franchise with a curriculum in place I am not too concerned about my TESOL units.

 

Should I be concerned about the fact that what I learned from my TESOL is rusty or is it not much of a concern?

 

Thanks in advance for any insight and related advice.
