Look for the “Online Learning Center” box on the left. Click on the “Student Edition” link. Select a chapter from the pull-down menu.

Click on the right-arrow to continue to the next problem. This process ends when you click on the right-arrow for the third time. To try to solve other problems from the same chapter, you will need to exit by clicking on, say, >Chapter XX> at the top, and restart “FE Exam Review.” Now you will be presented with all new, or a mixture of old and new, problems. After repeated trials, no new problems will appear. As I mentioned in class, some of the online problem statements have errors in them, and some solutions and answers are wrong. For this reason, I have prepared a separate document that lists the errors and corrections. You can access this document at: http://www.calstatela.edu/sites/default/files/users/u28426/felszeghy/fe_exam_review_rev3.pdf . Although I shared the errors and corrections with McGraw-Hill, the company has not made any corrections on its Website. The online problems are not numbered, except for being associated with chapter numbers. For this reason, I downloaded the online problems in no particular order, and numbered them consecutively in a decimal format, XX.X, where XX refers to the chapter number, and X stands for the sequence number. All the online problems numbered this way are included in the above “FE_Exam_Review_rev3.pdf” document under the heading: “Part 1, FE Exam Review, Online Problems and Solutions.” My own solutions, which you will find below, follow the problem numbering scheme I established above. I include sketches in my solutions to allow you to identify the problems to which my solutions apply without necessarily having to refer to Part 1 of the above “FE_Exam_Review_rev3.pdf” document. I wish you all the best on your computer-based FE exam!
