Students wishing to enroll in General Chemistry (CHE 1103) must take and pass the Chemistry Placement exam prior to registering for the class.

  • This test may be taken only once per year, so come prepared!
  • The fee for Chemistry Placement is $20 and is charged to the student’s UTSA account immediately following the test.
  • A scientific non-graphing calculator is permitted.

Log into ASAP to sign up for the Chemistry Placement exam; no walk-in slots are available. Students have 90 minutes to complete the exam.

If a student does not achieve the passing score of 21 out of 30 questions, he or she will be placed in Basic Chemistry (CHE 1073).

Additional Information on placing into Chemistry Courses if CHE 1103 is part of your major requirements:

Two options available:

1. Register for CHE 1103 Placement Exam

2. Enroll in Basic Chemistry (CHE 1073 ) course

Option 1 : CHE 1103 Placement Exam

– Students can register with Testing Services at UTSA to take this exam. You must achieve a passing rate of 70% (21 questions out of 30) to be able to register directly for General Chemistry I ( CHE 1103) and skip the semester of Basic Chemistry (CHE 1073).

– Recommended for students who have a strong knowledge of math and chemistry from high school.

Option 2 : Enroll or stay enrolled in Basic Chemistry (CHE 1073)

– Students can enroll in Basic Chemistry (CHE 1073) for the Fall 2017 semester.

– Must have obtained a grade of “C-” or better to enroll in General Chemistry I ( CHE 1103).

– Recommended for students who do not have a strong background in math and chemistry, or for students unable to complete option 1.

Assessment and LEarning in Knowledge Spaces is a Web-based, artificially intelligent assessment and learning system. ALEKS uses adaptive questioning to quickly and accurately determine exactly what a student knows and doesn’t know in a course. ALEKS then instructs the student on the topics he or she is most ready to learn. As a student works through a course, ALEKS periodically reassesses the student to ensure that topics learned are also retained. ALEKS courses are thorough in their topic coverage, and ALEKS avoids multiple-choice questions. A student who shows a high level of mastery of an ALEKS course will be successful in the actual course he or she is taking.

ALEKS also provides the advantages of one-on-one instruction, 24/7, from virtually any web-based computer for a fraction of the cost of a human tutor.

Do I need to purchase access? What does it cost?

Yes. You can purchase your 90-day access online during the registration process (see step 5) for $30.

How do I log-in?

1) Go to

2) Click on “SIGN UP NOW!”

3) Enter Course Code: NT4NA-QTWP9

4) Confirm that you are in the correct course.

5) You will now be prompted to enter your access code. You can purchase access on this page via credit card.

6) Fill out the student information web page.

7) Take the initial assessment.

You will be asked to solve approximately 20 to 30 problems. This will take you anywhere from 30 to 90 minutes. The system will save your progress if you log out.

Do not attempt to receive assistance from an outside source. The purpose of ALEKS is to determine precisely where you should start learning. For example, if you ask a Chemistry graduate student to assist you or if you use Google, ALEKS will assume you are advanced and will tailor your instruction accordingly.  As a result, you will likely become frustrated and miss important prerequisites. Conversely, if you fail to take the assessment seriously and answer questions randomly, you will waste time on material you already know.

The assessment covers the entire first-year material, so expect to receive problems you have no idea how to solve. This is no cause for concern; it is a placement test, not a final exam. You will not be graded on it, and there is no reward for doing better and no penalty for doing worse.

8) Learning Mode

After the assessment, you will see your ALEKS “pie.” This shows you what you already know, what you are ready to learn, and what topics you will eventually need to learn, and by what date.

You can begin working on topics by scrolling over your pie slices. Available topics will be hyperlinked and you can begin.
