Overview of the Chemistry Placement Exam and ALEKS Chemistry
Passing the Chemistry Placement Exam allows you to bypass the chemistry prerequisites for both CHEM-C102 and CHEM-C105. Registration for the exam is now free and gives you access to ALEKS Chemistry, which hosts the exam. You are first presented with an Initial Knowledge Check which covers about 130 fundamental chemistry topics with questions that adapt to the knowledge and ability of each student. If you score 51% or higher on the Initial Knowledge Check then you have passed the Chemistry Placement Exam and may discontinue use of ALEKS Chemistry. If you score less than 51% on the Initial Knowledge Check then you may take a Retest approximately once every two weeks when you feel you are ready, subject to the end of your subscription. Regardless of you how perform on the Initial Knowledge Check you may continue within ALEKS Chemistry to review, practice, and learn material from the topics covered on the exam, for as long as your account remains active, which is currently set at 18 weeks.
As you review, practice, and learn chemistry in ALEKS Chemistry, the system reports how many topics you have learned and mastered. Successful practice leads to topics learned. Periodic partial Knowledge Checks are automatically offered after a sufficient number of topics have been learned and cover only those topics recently learned; success promotes those recent topics from a learned status to mastered status. None of this progress is official; these checks are only for you to gauge your ability to pass an upcoming Retest. A Retest is essentially a repeat of the Initial Knowledge Check. Your several-week subscription to ALEKS Chemistry is divided into many time blocks (usually two-week periods) and you may take one Retest at any time during each time block. Failure to score 51% or higher on a Retest means that you must wait for the next time block for another Retest; however, you may practice freely within ALEKS at any time (except during a Retest or the Initial Knowledge Check). It is okay to skip a Retest and take the next one instead. Once you score 51% or higher on a Retest, then you may discontinue use of ALEKS Chemistry.
One purpose of the Chemistry Placement Exam is to give an accurate measure of your current skills so that you will place into a course where you will have the best opportunity to succeed. Therefore, while you are taking the Initial Knowledge Check and Retest, it is important that you do not consult with any other source for help (friends, family, internet searches, textbooks, etc.). Use of outside resources may result in you being placed into a course for which you are not prepared. However, another purpose of ALEKS Chemistry is to provide you with a way to refresh your previous knowledge and skills – and even to learn some chemistry on your own. For this endeavor, you are advised to use all resources available to you to best learn and practice as you prepare for your Retest.
Scores for this test are regularly recorded in your One.IU account in the test credits section as SBCHM, typically at the beginning and middle of each month. For the Fall and Spring semesters, passing scores on an Initial Knowledge Check or Retest must be received by Friday of the first week of classes (Fall and Spring semesters) so that scores can be posted on Saturday for the last day of registration (already one week “late”).
You will need your IU username and student identification number to identify you as an IU student during this process. For help during this registration process, please contact ALEKS Customer Support by visiting http://support.aleks.com. Note: There is typically a two-week period of time after the end of registration for classes each term where we shut down registration for ALEKS and do not offer the placement exam within ALEKS – however, students who already have access to ALEKS will continue to be able to use ALEKS for the purpose of studying and reviewing, but no new Retests will be offered during this time.

- Full name
- email address – Use your IU email account
- Student ID – Use your IU student number
- Be sure to record the ALEKS USERNAME and ALEKS PASSWORD you choose so you can re-enter the ALEKS platform. They do not need to be the same as your IU username and password.
- Registration is now complete. You may log off and return to ALEKS Chemistry at a later time starting with step (1) in the next section … or continue right now in ALEKS Chemistry starting at step (2) in the next section.
Using ALEKS Chemistry (After registration and through the Initial Knowledge Check)
- Sign in at https://www.aleks.com using your ALEKS username and ALEKS password.
- Select Chemistry Placement Exam from My Classes
- You will be greeted with a few welcoming windows before you are directed to the main menu.
- After a few clicks of the mouse on some more tabs you will be directed to the Take the Tools Tutorial. Click GET STARTED and proceed through the tutorial to familiarize yourself with the testing environment.
- Once you have passed the tutorial you may take the Initial Knowledge Check. This is your first chance to bypass the prerequisites for both CHEM-C102 and CHEM-C105. If you are ready to begin, please click START KNOWLEDGE CHECK. At the end of the Initial Knowledge Check, you’ll be shown a results screen indicating how many topics out of the total number that you have mastered. You must master 51% or more of the topics to pass the Chemistry Placement Exam.
- There is no special message to indicate whether you have passed the Chemistry Placement Exam based on the Initial Knowledge Check. If you mastered 51% or more of the topics, then you have passed the Chemistry Placement Exam and may discontinue use of ALEKS Chemistry. If you mastered 50% or fewer of the topics, then you have not passed the Chemistry Placement Exam and you may wish to continue using ALEKS Chemistry to take a Retest later. You will see an image like the one below when you finish the Initial Knowledge Check. Although the favorable message “Nice job, Matt” is displayed in the image below, a score of 28% is not sufficient to pass the exam. This student can use ALEKS Chemistry to review the topics he has not mastered before taking a Retest.
Using ALEKS Chemistry (After the Initial Knowledge Check)
To continue using ALEKS Chemistry to learn and review topics to prepare for a Retest (or just for the sake of learning), please follow the commands that pop up on the screen after the report of the results from your Initial Knowledge Check. Eventually ALEKS Chemistry will take to you the Learn mode. Click on the menu icon (≡) at the top left of the screen to reveal a menu. Your screen should now look mostly like the image below except that colored boxes have been added here to highlight certain sections. The small green box is the menu button which shows/hides the vertical menu on the left of the screen.
The two items highlighted in red boxes show the same information: a record of your learning progress. Immediately after the Initial Knowledge Check this data shows that the student scored a 28% on the Chemistry Placement Exam (mastered 37 of 134 topics). Thus the student did not pass and should take a Retest after reviewing and learning more material. Had the student mastered 68 (or higher) of 134 topics then the student would have passed the exam with a score of 51% (or higher). That student would be done. As you learn and practice within the ALEKS system, the number of mastered, learned, and remaining topics in the top-right red box will change, as will your Class Progress in the other red box. These numbers are NOT official once they change from their starting values. However they do serve as an indicator of your knowledge and skill. Once you have mastered 68+ topics (shown in the top-right red box or under Class Progress in the bottom-left red box), then you are ready for a Retest.
Please note that the due date under “Class Progress” in the lower-left red box is meaningless; unfortunately, it cannot be removed from the ALEKS Chemistry website.
The numbered parts of the menu in the screen image are discussed below.
- This is where you learn and practice topics that you have not yet “mastered”. There is lots of textbook-like information available here if you get stuck on a question or wish to study material.
- You can review mastered topics here.
- This is where you access your Retest. You have multiple opportunities for a Retest.
- This is where you check your Retest grades. A score of 51% or higher on any Retest means you are done.
- This is like a chemistry encyclopedia.
