Is this Economics program out of date?

A friend is letting me borrow Notgrass Econ for next semester but I realized it is the 2009 version and it looks like they have a newer version (2016) out .  Will this be ok to use or will it be too out of date?  Econ is not my thing, so I don't know how much this stuff changes in that amount of time.  I would prefer to not have to buy it if this will be fine since this is for my youngest kid, but I want up to date info.  Thanks

Another question: Do you have the 2009 versions of the student notebook and the tests? If you don't I think you might have trouble lining it up. 

I didn't look at the 2009 version so I cannot speak to out of date.

My personal plan is to use an older econ textbook, and I can have them look up things online if necessary to update it.

The Notgrass 2009 quiz and exam pack is available to purchase online if you don't have them. So if you have the student notebook for 2009, you're good to go.

Thanks-I did know about the online quiz/test pack but  I do not have the student notebook, just the two textbooks.  Thanks for pointing that out.  I'll have to see if I can get that.
