Chemistry 1A: Dr. Jeffrey A. Mack


Chem 1A S2015

To add chem 1A go to the discussion sections on Monday & Tuesday of week 1.

You must have a current passing diagnostic score and meet the course math requirements.

Students on the discussion waitlists will be added 1st by position.

Chem. 1A Students for Spring 2015 Please read this note carefully!

There will be slightly different set of course materials for the two lecture sections, Section 01(MWF 9 am) and Section 14 (MW 4:30pm).

As soon as you enroll in the course, go to the SacCt course website associated with your section and read the course requirements very carefully.

DO NOT purchase or order any of your course materials until you have carefully read what is posted on SacCt for your lecture section.

By enrolling in the course, you are responsible for obtaining the correct course materials for your section. Failure to do so may result in you purchasing materials that are not specific your your section.

If you are purchasing your course materials from the CSUS bookstore pay close attention to which materials are specific to the section in which you are enrolled.

I will be sending out email and posting announcements via SacCt soon. Please do not ignore or disregard this information.

Dr. Mack

Placement testing for F2014 will begin in late November, go to HERE for dates and locations.

Chem 1A/1E: All students who want to register for chem 1A or 1E must pass the chemistry diagnostic exam before instruction begins. The exam will not be offered after the semester begins. NO EXCEPTIONS!

It is most beneficial for students to take the exam as early as possible so that when their registration time comes they are ready to go as opposed to having to wait until the next diagnostic.

  • The test can only be taken once per semester and your score is good for 2 semesters.
  • You must score a minimum of 35 or greater enroll in chem. 1A/E.
  • The exam cannot be repeated for a better score during a  semester's registration period. If you score below 35 then you must wait until the next semester to retake the exam.
  • If your score is older than two semesters, you must re-take exam.
  • Scores will show in your My Sac State Student Center once you take the exam.
  • Scores for F14 are already in the system so if you passed the exam, your score has been recorded.
  • Scores for S14 do not count towards S15. Score for F14 will count for S15.
  • If you do not meet the math pre-req's, you will also need to take the IAD. See below.

Chem. 1A Math Requirements:

Upcoming IAD Exam Dates (Registration with the Math Department required):

The math department will have dates for the IAD up on their web site.

1. Have passed MATH 11 with a C or better so that they are ready for the next level math class.
2. Have taken and passed or be concurrently enrolled in a math class ABOVE  MATH 11.
3. Have a IAD (Intermediate Math Diagnostic Test) or Calculus Readiness Test score of 27.

Confirming Math Prerequisites:

Students may show transcripts or their IAD Score. If they show the IAD score, it must be 27 or greater.

Student  transcripts or class schedules must show the following:

1. A passing score of C or better in math 11.
2. Any math course where math 11 is a prerequisite such as math 26A/B, math 29 or higher.
3. Stats 1 & 50 DOES meet the requirement if taken at CSUS only.

Math 17 DOES NOT meet the requirements as math 9 is prerequisite.
Math 24 DOES NOT meet the requirements as math 9 is prerequisite.

Chem. 1A Diagnostic Placement Exam

The Chem. 1A Diagnostic exam will be offered during finals week and over the summer break:

Beginning this semester, the Department of Chemistry at CSUS will require that all students enrolled in chem. 1A have taken and met the minimum score on the diagnostic placement test prior to the beginning of classes.

Students that fail to take the test by one week before classes will be administratively dropped and their seats in the course will be filled by those with passing scores on the wait lists.

Please  follow this link to find out more information on the exam.

The exam has 60 questions broken into three parts:

I: Basic math skills needed for chemistry
II: General chemistry knowledge topics
III: Specific chemistry topics

All Students must take the exam to enter chem. 1A.

A minimum score of 35/60 (58.3%) is set at the 65th percentile of all students taking the exam.
This equates to a projected grade of D+/C- in chem. 1A.

Diagnostic exam FAQ's:

Can I take the exam more than one time?

No. Students may only take the exam one time per registration cycle.

I took the exam in a previous semester and scored over 35, do I need to take the exam again?

Passing exam scores are good for one year.

I took chem. 4 and passed with a C or better do I need to take the exam?

Yes. Students that have taken chem. 4 must also take the exam, however  so long as you have a grade of C or better in chem. 4, your score will not affect your enrollment in chem. 1A.

I took another chemistry class at a different college, does that count as passing chem. 4?

No. CSUS does not accept grades from courses equivalent to chem. 4 from other schools.

I am repeating chem. 1A, do I need to take and pass the diagnostic, even if I passed it last semester?

Yes. If you failed to pass the course on your first attempt, then you need to show that you have the requisite preparation for your second attempt by passing the exam with a score of 35 or higher.

What if I don't take the exam before school starts, will I be dropped?

Yes you will. No exceptions.

Required Textbook Package and Additional Class Materials

Chem. 1A will be using "Chemistry a Molecular Approach", 3rd ed. by Nivaldo J. Tro

Tro 3rd Ed.

  • The selected solution manuals and study guide are optional.
  • You will need a calculator that can perform scientific calculations and a notebook for discussion.
  • I also suggest you have a 3-ring binder or some other portfolio to keep track of your papers.
  • You will also need chemistry department approved lab goggles and a lab coat to be worn in the lab sections.
See the Hornet bookstore web site or here for textbook information.

It is expected that you have all of your course materials prior to be start of classes. Issues such as finical aid, fees or scheduling issues are your responsibility. If you are enrolled in the class,  then it is up to you to be prepared. I will have review assignments up on mastering chemistry in mid August.

Please see SacCt for information about your HW for S2015

Lecture Section 01 will use ALECKS
Lecture Section 14 will use Mastering Chemistry

All lab and discussion materials will be available for free download on the course SacCT site when classes begin.

If you are a new student or have never used SacCT, please go through the student tutorials and registration information found here
