Find Your Study Plan

The answer key shows where in this chapter to find explanations for the questions you missed.
Here’s how you should proceed based on your Diagnostic Test score.

5: Superb! You have a solid grasp of the essentials of solid geometry, and if you’re pressed for time,
you might consider skipping this chapter. If you want to try your hand at a few more solid geometry
questions, go straight to the Follow-Up Test at the end of this chapter.

3–4: Good! If you can get three or four of these relatively difficult questions right, then you have a
decent understanding of solid geometry. If you’re pressed for time, you might consider skipping this
chapter. Alternatively, you might want to look over the parts of this chapter that deal with the one
or two questions you didn’t get right. If you just want to try your hand at a few more solid geometry
questions, go straight to the Follow-Up Test at the end of this chapter.

0–2: Solid geometry is not your forte right now, but since it accounts for only three or four questions
on the test, it may not be worth worrying about. If you’re pressed for time and are confident with
the other test topics, you might consider skipping this chapter. But if you have the time, you should
read the rest of this chapter, study the examples, and then try the Follow-Up Test at the end of the
chapter.
