##### AB 705

State law AB 705 changed the way that students are placed into their Math courses. Some prerequisite courses have been eliminated. Other courses now have a support component to help students review the prerequisite material. The video below will guide you in choosing which Math class is right for you.

**Placement**

- Starting fall 2019, all incoming students will be placed into transfer-level math regardless of their preparation. There will be no more placement tests.
- Students will save money and time since they will be able to go straight into a transfer level course.
- In order to support our students in these difficult classes we have developed co-requisite classes that will be linked to many of our beginning transfer level math courses (Math 110, 115, 120, 130 and 141). These courses are designed to supplement the material of the course with review material that students need in order to be successful in the course.
- Students will be placed either into the stand-alone course or the course with the linked co-requisite based on their high school GPA. · Students may use our new online Guided Self Placement Tool in order to get placed into a math course. They can also see a counselor to help determine their placement.
- If a student is placed into the stand-alone course, but would prefer to have the support of the paired course they can always opt to take that course instead.

The Mathematics Department is dedicated to providing each student with an education that stresses high quality instruction. Our dynamic, knowledgeable faculty provides a supportive atmosphere which includes mentoring students through a “hands-on” approach to instruction. Students will gain the skills they need, whether they are working to meet professional goals, earn an AA or AS degree, or plan on transferring to a 4-year university.

##### What we offer:

- a full range of mathematics courses
- Supplemental Instruction in numerous courses
- courses taught using free Open Educational Resources
- the provision of a Math Learning Center where students may receive additional assistance
- the sponsoring of an on-campus Math Club which competes twice a year in a competition hosted by the American Mathematical Association of Two-Year Colleges Student Mathematics League

##### About the Department

Our department offers classes both throughout the day, and in the evenings. Classes are typically no more than 35 students, providing a low teacher-to-student ratio and increasing direct access to instructors. We offer Trigonometry, Finite Math, Statistics, College Algebra and Intermediate Algebra in online and/or hybrid formats. Our students have an exceptional rate of transfer to and success in U.C. system schools and other 4-year universities and colleges.
