This song gives some practical advice and encouragement on taking tests, which is always a great cross curricular topic for schools. Passing the test certainly applies to school, but more than that, it applies to life in general. The song teaches a great life lesson: Do everything you know to do to accomplish your goal, and you'll have no regrets, knowing you did your absolute best.
The song is written in two parts, though part 2 is optional. Rehearsal tracks for both parts are included in the kit. (from Music K-8, Vol. 24, No. 5)
