If "no", then CHEM 110 is probably the best choice. You will be at a disadvantage if you enroll in CHEM 142 without high school chemistry.
If "yes", then CHEM 142, 143, or 145 are appropriate introductory courses. If you're uncertain whether the high school course you took was advanced enough, or if you took chemistry sometime ago and you feel that you need a refresher course, then beginning with CHEM 110 may be a good choice. It's better to be well prepared when taking the general chemistry sequence than to rush ahead into a course that is too advanced.
CHEM 120 is not designed to prepare students for CHEM 142, 143, or 145; rather, it is the first course of a three quarter sequence (CHEM 120, 220, & 221) that is for students planning to pursue majors in the allied health fields such as nursing and other selected science majors. Only 6 credits are allowed for courses from CHEM 120, CHEM 142, & CHEM 143 if more than one of these courses are taken. CHEM 120 can not be used for the chemistry or biochemistry majors. If you are uncertain about which course to take you should contact chemistry/biochemistry advising.
Math is the universal language of science and an important component of the chemistry and biochemistry curriculum. At the UW, entering students who do not have college credit for math will need to take the Math Placement test at the Office of Educational Assessment before registering. This test will indicate the math level for which you are eligible to register. The recommended level of math placement for CHEM 120 and CHEM 142 is MATH 120 (pre-calculus). If you placed below MATH 120 and are hesitant about your math skills, it is advisable to delay taking CHEM 120 or CHEM 142 until you are at the level of MATH 120. Ideally, CHEM 142, 152, 162 should be taken concurrently with the calculus sequence, MATH 124, 125, and 126. For Accelerated General Chemistry (CHEM 143) and Honors General Chemistry (CHEM 145), strong math skills are essential. For CHEM 143 the official prerequisites is placement into MATH 124, and CHEM 145 requires MATH 124 which can be taken concurrently
Several majors on campus require chemistry as a degree requirement. However, the required sequences vary from major to major. See the Degree Programs website or consult a department advisor for specific information. If you are undecided about a major you should investigate the various degree programs for which you have an interest, and then choose the chemistry sequence that will meet or exceed the requirements for all, as well as keeping your options open. If you want help in choosing a major talk with the departmental advisors and/or attend one of the Gateway Center's Undergraduate Advising Office workshops on "How to Choose a Major", which are offered frequently during the academic year.
If you plan to pursue medical school or another health science professional field, check the prerequisite requirements for the specific program to see how it impacts your choice of major. Always take the more comprehensive sequence to keep your options open (that usually means the CHEM 142 or more advanced sequences).
Many programs' standards of admission are above the stated minimum requirements. For example, although a nursing school catalog may say that CHEM 120 and 220 are adequate prerequisites for admission, you should check with the advising staff to ensure that sequence is really the best sequence to remain competitive for admission. If a medical school says you don't need a degree to be admitted, ask them how many students in the entering class did not have a bachelor's degree. In order to gain admission to the highly competitive programs in health sciences, you usually have to do more than meet minimum requirements. Again, you will be covering all your bases by choosing the CHEM 142 or more advanced sequences. Further pre-med, pre-dental, pre-pharmacy information is available at UW's Pre-Health Advising web page. You can also receive additional information about these pre-professional programs at The Undergraduate Advising Office, part of the Center for Undergraduate Advising, Diversity & Student Success, in 141 Mary Gates Hall.
CHEM 145 is open to students with a score of 4 or 5 on the AP test;or a 5, 6, or 7 on the High Level Chemistry IB exam or those who have passed the general chemistry honors placement test offered by the UW Educational Assessment Office. Students receiving a borderline passing score should consult with the chemistry advisors regarding appropriate placement. Students should be aware that CHEM 145 assumes full mastery of the basic concepts of elementary chemistry so the course will not review this material. The expectation for math and problem solving proficiency is also high in the honors courses. The CHEM 145 information sheet contains a complete listing of prerequisites, exam information, source materials, and sample exam questions indicating areas and levels of knowledge expected on entry.
Chem 143 is open to students with a score of 1 or higher on the AP Chemistry test or those who have passed the Chem 142 Placement Exam offered by the Office of Educational Assessment Placement into Math 124 is also required for enrollment. Students should be aware that CHEM 143 assumes mastery of the basic concepts of stoichiometry and gas laws and will be moving at a faster pace than CHEM 142. Excellent problem solving and mathematical reasoning skills are required for success in this sequence.
7.Did you take the Advanced Placement (AP) Test in Chemistry or the IB Higher Level Chemistry Exam?
Students who earned a chemistry AP exam score of 5 receive credit for the general chemistry sequence (CHEM 142, 152 and 162). Students who earned a chemistry AP exam score of 4 receive credit for the CHEM 142 and 152. Students who earned a chemistry AP exam score of 3 receive credit for the CHEM 142. However, students who are interested in chemistry or biochemistry as a major are strongly encouraged to consider honors general chemistry if they meet the pre-requisites. More information about the UW AP policy is on the UW homepage.
Students who earned a Higher Level Chemistry IB exam score of 7 receive credit for the general chemistry sequence (CHEM 142, 152 and 162). Students who earned a Higher level Chemistry IB exam score of 6 receive credit for the CHEM 142 and 152. Students who earned a Higher Level Chemistry IB exam score of 5 receive credit for CHEM 142. However, students who are interested in chemistry or biochemistry as a major are strongly encouraged to consider honors general chemistry if they meet the pre-requisites. More information about the UW IB is on the UW homepage.
If you took college-level chemistry courses in high school as a part of the Running Start Program, you're eligible to continue on with the next level of chemistry. If your credits have been transferred and posted, the UW web registration system will allow you to register for the appropriate courses. More information about Running Start can be found on the UW homepage. If you have questions about your Running Start chemistry credit, consult with a department advisor.
Introductory chemistry courses consists of three or four weekly lectures taught by a professor, one weekly hour-long quiz section taught by a teaching assistant (TA), and three hour labs monitored by the TA. Your TA serves as a link between you and your professor, passing on information and clarifying answers to questions you might have. TAs are also the primary graders of your homework, tests, and lab reports.
Although there may be multiple sections of the course, each section covers the same chapters in the same textbook and the same labs as the other sections. However, the instructor will influence the course through their different teaching styles and emphases placed on different material. Students can learn more about individual professors by going to the Department of Chemistry Faculty Directory. Research interests and publications are included in the short biography of the professor.
The course, including lecture and lab, has a single grade. Attendance at your scheduled lab is mandatory. The graded work is a mix of the values assigned to lab reports, pre-labs, quizzes, and midterm and final exams. The individual instructor will publish their own grading information in his or her section syllabus. Some of these are available in the Course Index.
