1.1 About the CLEP Precalculus Exam

1.1 About the CLEP Precalculus Exam

Quick Answer: CLEP Precalculus is a College Board exam of approximately 48 questions in 90 minutes, split into a 25-question calculator section (50 minutes) and a 23-question no-calculator section (40 minutes). It is scored on a 20–80 scale, and the American Council on Education (ACE) recommends granting 3 semester hours of credit for a score of 50. The fee is $97 plus the test center's or remote proctor's administration fee.

The CLEP Precalculus examination measures whether you have mastered the skills and concepts a first-semester calculus course assumes you already own. Passing it can replace a one-semester college precalculus course. The College Board is explicit about what that means in practice: "A large portion of the exam is devoted to testing a student's understanding of functions and their properties." If you learn nothing else from this guide, learn functions.

1. Exam Format

The exam is delivered in two separately timed sections, and the calculator rule changes between them.

Totals: ~48 questions, 90 minutes. Most items are five-option multiple choice (A–E), but some questions require you to type a numerical answer into an entry box rather than pick a choice. Numerical-entry items have no options to eliminate and no partial credit, so read their rounding instructions carefully — an official sample item asks for an answer "to the nearest tenth of a year."

Practice-format note: The quizzes throughout this guide use four options rather than the exam's five. The reasoning you practice is identical; just expect one extra distractor on test day, which slightly lowers the value of blind guessing.

The calculator is a tool, not a crutch

Because Section 2 forbids calculators entirely, roughly 48% of the exam is calculator-free. Every exact value you can produce from memory — the unit circle, $\log_2 8$, $\sqrt{50} = 5\sqrt{2}$, the discriminant of a quadratic — is time you do not spend hand-computing. Conversely, in Section 1 the graphing calculator is genuinely powerful for finding intersections, zeros, and maxima. Practice both modes deliberately, and learn the TI-84 Plus CE interface before test day.

2. Content Outline and Weights

The College Board publishes six content areas with approximate percentages:

Two features of this table decide how you should study.

First, Representations of Functions is the single largest area at 30%. The College Board describes it as the ability to recognize and transform functions "presented symbolically, graphically or in tabular form," and it names the families you must recognize on sight: linear, quadratic, absolute value, square root, polynomial, rational, exponential, logarithmic, trigonometric, inverse trigonometric, and piecewise-defined. A question may hand you a table of values and ask which function fits it — a form many textbooks under-drill. Section 3.4 of this guide exists specifically for that.

Second, the published 15% for trigonometry understates it. The College Board attaches a footnote to that line: trigonometry "permeates most of the major topics and accounts for more than 15 percent of the exam. The actual proportion of exam questions that requires knowledge of either right triangle trigonometry or the properties of the trigonometric functions is approximately 30–40 percent." Trigonometric equations sit inside area 1, trigonometric graphs inside area 3, and periodic models inside area 6. Budget your study time against 30–40%, not 15%.

3. Scoring and Credit

CLEP scores are reported on a 20–80 scaled score. There is no percentage score and no letter grade.

• ACE credit recommendation: a score of 50 earns 3 semester hours, equivalent to a course grade of C.
• Each college sets its own policy. A school may require a higher score, may grant the credit toward a distribution requirement rather than a specific course, or may not accept the exam at all. Confirm your institution's policy before you register.
• No penalty for guessing. Scores are based on the number of correct answers, so never leave a multiple-choice item blank.
• Retake policy: you may not retake an exam of the same title within three months of your test date. Violating this voids the administration, cancels the score, and forfeits the fee.

Cost

The exam fee is $97, plus a separate administration fee charged by the test center or remote proctoring service. Many colleges and all branches of the U.S. military fund CLEP exams for eligible candidates — ask before you pay out of pocket.

4. How to Use This Guide

The chapters follow the official outline, and each section ends with quiz checks written in the exam's style.

1. Chapter 2 rebuilds algebraic fluency — the machinery every later chapter assumes.
2. Chapter 3 is the conceptual core: what a function is, and how it looks symbolically, graphically, and in a table.
3. Chapters 4–5 work through the function families one at a time.
4. Chapter 6 covers analytic geometry: lines, circles, and the three conic sections.
5. Chapter 7 covers the trigonometry strand, which is larger than its 15% label suggests.
6. Chapter 8 applies everything to modeling — the payoff area.

A realistic plan is 40–60 hours over 4–8 weeks if your algebra and trigonometry are recent. Work every example with a pencil before reading its solution, and do at least half your practice with no calculator in reach.
