If you want her to have "seen" the format and at least understand WHAT content will be presented, that's probably fine. Practice tests-- at least a couple of them... but don't go overboard.
I echo the other cautions about active PREPPING of topical coverage. That won't tell either one of you a thing. Oh, sure, it might look good, but ultimately, you'll be in the position of wondering if comparisons are valid, given that the idea in that testing population (that is, out of level testing using EXPLORE) is that they have NOT seen so much of the content. In other words, an HG child who has been "prepped" will almost certainly OUTSCORE a PG child who hasn't.
The country may be becoming more Bostonian
over time, spending more time preparing for standardized tests. For example, the Russian School of Math
http://www.russianschool.com/2013-award-winners , which has branches in MA and elsewhere, boasts of its students' results on talent search tests. If we have reached the tipping point where most talent search participants are preparing, it is the students who not prepare who are getting the most biased results (in their case, downwards). Another argument for preparation is that there are Tiger children of Tiger parents who are motivated to study (vocabulary, for example) by the prospect of taking the SAT again.
