ALEKS is an online educational product offered by McGraw Hill Education.

If a student scores 0-20 questions correct (0-57%) on the Chemistry Placement Exam or CPE (placing them into CHEM 1301, Preparatory Chemistry) the student has the option to demonstrate content mastery through the ALEKS (Assessment and Learning in Knowledge Spaces) program. Entry into CHEM 1307 can be permitted by achieving 95% content mastery in TTU's ALEKS course. The last day to complete the ALEKS course in time to take CHEM 1307 in the Fall of 2014 is Sunday August 17, 2014 at 11:59 PM. From the time of registering for ALEKS you will have access to the system for 11 weeks, although only scores attained prior to Sunday August 17, 2014 at 11:59 PM are eligible for enrolling in CHEM 1307 for the Fall 2014 term.

Students scoring 21-35 questions correct (60-100%) on the CPE may also register for and use ALEKS to prepare for CHEM 1307.


  1. Go to the ALEKS website: http://www.aleks.com/sign_up
  2. Enter or Copy and Paste the following course code into the box labeled "Using ALEKS with a Class?": L6TX4-NEQ3E
  3. Select the course "1307 Remediation (College)"
  4. It is best that you register using your ttu.edu email, even if you already have an ALEKS account under a different email address. Also ensure you have accurately entered your Texas Tech ID number, known as the "R-number" to ensure that your score is accurately transferred from ALEKS to Texas Tech University.
  5. ALEKS may require you to install a browser plug-in. If so, after installation, it may also be necessary to close the browser and log back in to continue.


After completing ALEKS registration, you will enter a guide that demonstrates how to use ALEKS. ALEKS is an adaptive system that tailors the questions and material it presents to you based on what you are ready to learn. It does this by first requiring you to complete an initial assessment after learning how to use the ALEKS system. ALEKS will then determine which topics need to be covered in subsequent learning modules.

The content reviewed in ALEKS includes math topics such as fractions, algebra, rules for exponents, graphing, scientific notation, and significant figures along with chemistry topics like naming binary ionic compounds and calculations involving limiting reactants and precipitation reactions, to name but a very few of the 140 total course topics. These topics were chosen to be consistent with the learning outcomes and material from CHEM 1301, Preparatory Chemistry.

We cannot provide support for the ALEKS system. Please contact ALEKS directly for technical support.
