CBEST Mathematics Test

On the CBEST Math Section

The CBEST Mathematics Section contains 50 multiple-choice questions.

There is no specific time limit, as you have four hours to complete the entire exam. Spending about eighty minutes is recommended.

You need to answer approximately 60 percent of the questions correctly in order to pass the Mathematics Section of the CBEST.

Math Skill Areas & Topics

The test covers three three major skill areas:

— Math Topics covered in Estimation, Measurement, and Statistical Principles

• Standard units of length, temperature, weight and capacity
• Measure length and perimeter
• Estimation of answers using arithmetic
• Statistical principles such as averages, ratios, and proportions
• Basic probability
• Interpret meaning of standardized test scores

— Math Topics Covered in Computation and Problem Solving

• Basic operations of addition, subtraction, multiplication, and division
• Solving algebraic word problems
• Determining whether enough information is given to solve math problems.
• Recognizing multiple methods of solving a word problem

— Math Topics covered in Numerical and Graphic Relationships

• Solving questions involving changes in data from one year to the next
• Using rounding rules correctly

• Understanding logical connectives
• Using information presented in bar, line, and pie charts to solve math problems.

Test Preparation

Find out what you know, how well you know it and what you don’t know.  Become familiar with the topic, the question, the solution approach and the steps to get the result,  Then review at least three times spread out  in time and using different question orders.

First, take the test below  without revealing any answers. 

Study your response to each question and compare with the given solution approach and the”show-the-work” steps for the correct answer.

Repeat reviewing the topics and questions to familiarize yourself with the questions, the solution approach and finally the “show-the-work answers. Before revealing any answers formulate an answer in your own words.

Test Questions  1-15; Estimation, Measurement, and Statistical Principles


—-  1.    During a semester, a student received scores of 76, 80, 83, 71, 80, and 78 on six tests. What is the student’s average score for these six tests?.

Find an average score  – given six scores.  An average of N numbers is the sum of the N numbers divided by their number N.    The sum 76+80+83+71+80+78 =  468. The average is  468/6 = 78.  The average score for the six tests is 78.


—- 2.   On the three sections of a math test, a student correctly answered the number of questions shown below. What percent of the questions on the entire test did the student answer correctly? Section/Total Number of Questions/Number of Questions Correctly AnsweredAlgebra / 20 / 17;  Trigonometry / 15  / 11 ;  Geometry   25  / 20

Find per cent, P, of test questions answered correctly, C, given the number of total questions, T,and those answered correctly for each of 3 tests.  Percent, P = 100 (C/T).  T = sum of  the 3 questions on each test  – or T = 20+15+25 = 60.  C is the sum of the correctly answered questions on each of)) the three tests – or C = 17+11+20 = 48. And so, P = 100(48/60) = 4800/60 = 80%.  Students correctly answered 80%  of the questions on the entire test.
