Scoring High on Iowa....Do I really need the Teacher's Edition?

[Holly IN]

I am getting ready to order this through Rainbow Resource. They offer two different kinds of test prep for Iowa. One is scoring High with student and teacher ed sold sep. and the other one is a Iowa test prep which looks like it is directly from BJU and much cheaper.

I am tempting to go for the cheaper one. HELP

I've never used a teacher guide for test prep. I vote go cheap.
