Module Three : Pretest

This page contains the Pretest for Module Three.

Each MACH 2010 module begins with a Pretest and ends with a Posttest. Each MACH 2010 test page contains 10 questions each worth 10 points for a total of 100 points. Please be sure you read and understand the following instructions before proceeding.

• You must complete all past work prior to beginning this module. Please ensure that you have submitted all assignments from past modules before beginning this module. Once you begin a new module we will no longer accept assignments or tests from past modules.
• You must submit a Pretest prior to starting this module. Any attempt to access this module's content (other than the HOME and GUIDE pages) prior to completing this Pretest will result in a failing grade.
• Answer all questions. Before you submit your Pretest please be sure you have answered every question and included your name.
• Press SUBMIT when you are done. If you leave the test page prior to pressing submit you may lose some or all of your entered responses.
• Submit only one Pretest. If, for whatever reason, you need to submit another version of the Pretest please indicate this in the space provided at the bottom of your test page. Please note that we cannot accept resubmitted tests after you start the module.

Warning!

Failure to observe testing procedures may result in lost test scores. Any deliberate attempt to circumvent or otherwise tamper with the MACH 2010 test pages will result in immediate expulsion from the program. If you suspect that you have accidentally or otherwise violated any of the rules stated above please email MACH 2010 Technical Support immediately.
