If you are using lessons from LTF's Graphical Displays (Mod 4), Probability (Mod 6), or Bivariate Data (Mod 10) modules, your students will likely be able to complete some of the free response questions from the AP Statistics exams given in the past. Seriously!! Anyone can access these questions and the answer keys from the College Board website; you need not be an AP Stats teacher or even registered as an Education Professional with the College Board. I've looked over the released questions from the 2003-2011 exams and compiled a list of the questions that relate well to the topics in the LTF training modules above. Note: If you were trained on Year 2 prior to this summer, be aware that there are some new lessons in Mod 6 (Probability) that would address the independence of events topic.

Anyway, first you would go to the AP Statistics Exam homepage:
apcentral.collegeboard.com/apc/memb.../8357.html

Then as you scroll down the page, you see links to the FR questions and to the solutions going back to 2003. Here are the questions (or parts of questions) that I think are accessible by Pre-AP students whose teachers have used the appropriate LTF lessons:

2011 2ab (probability from a 2-way table, showing independence)
2011 Form B 1 (histogram, mean v. median), 6ab (interpret slope of linreg eqn)
2010 Form B 1 (boxplots, stemplot), 5abc (probability from a 2-way table, showing independence), 6ab (interpret slope of linreg eqn, meaning of a residual)
2009 6b (cool question about skewness)
2009 Form B 1ab (boxplot, median, IQR, transformations)
2008 1 (boxplots, transforming data, shape, mean v. median), 4 (scatterplot + interpretation)
2008 Form B 1a (dotplot, shape of distribution), 6ab (scatterplot + table interpretation)
2007 Form B 1 (stemplot, characteristics of distribution, measure of center), 4 (scatterplot, linreg, residuals)
2006 1 (dotplots, measure of center)
2005 1a (back-to-back stemplots)
2005 Form B 1 (stemplot, all of CUSS)
2004 1 (parallel boxplots)
2004 Form B 5a (parallel boxplots)
2003 1ab (parallel boxplots)
2003 Form B 2 (probabilities from a 2-way table, showing independence)

MC questions in the Course Description:
1 (scatterplot residual)
3 (probability--can be done with a tree diagram!)

There are more scatterplot and residuals questions in the 2003-2006 years that are good, but they were all about reading computer output during that time. If the teacher pulls that part and actually provides the linreg equation, those questions could also be used!
