LS 7ABC & LS 107 FAQs

LS 7ABC & LS 107 FAQs

What prompted the restructuring of the LS Core courses?

After two years of active discussion among the Life Sciences (LS) departments, Chairs, and faculty, the LS Core have concluded that a curricular change of the current sequence of courses is necessary and desirable to optimize student learning and accessibility. The Core will continue the current offerings of LS1-4 during Fall 2016 to Spring 2018 as we transition into the new 7 series.

Will the 7 series courses directly correspond to LS 1/2/3/4 or has the content changed? If so, what are the foreseen advantages of this restructuring?

While there is not an exact correspondence between the two series, much of the material in 7A is covered in LS3 – 7B is covered in LS1, and 7C in LS2. However, since the content of the 1-2-3-4 series is spread among 7ABC+LS107 in a different way, students will not able to switch between the series or use courses from one series to repeat courses from the other series.

Introductory material currently covered in LS4 (mendelian inheritance, and an introduction to genetics and genomics) has been integrated into 7B and 7C. LS7B will contain three weeks of genetic material currently covered in LS4. This is a sufficient amount of introductory genetics to prepare students for many upper division courses that require Mendelian genetics.

If I started LS 1/2/3/4 series, can I switch over to the LS 7 series?

No, you cannot switch over to the 7 series if you already started LS1-4 series. The 7 series will begin in Fall 2016 with limited enrollments for incoming students only. LS 1/2/3/4 will phase out by Spring 2018, and students currently enrolled in the sequence should plan to finish by then.

How will changing from LS 1/2/3/4 to the 7 series affect fulfilling my pre-med requirements?

The restructuring of the LS Core series will actually make it easier and faster for students to fulfill their pre-med requirement by switching from 4-classes to a 3 quarter model.

Is the LS7 series a sequence? Do I have to take and pass 7A in order to take 7B? Or can I move onto 7B and later go back and re-take 7A?

The numbering of these courses indicates that they are not considered three separate courses but rather a single integrated course taken over a one-year period. If a student does not pass 7A the first time around, the student must retake and pass 7A in order to move onto 7B.

Students will not be able to repeat LS 1 after Fall 2017, LS 2 after Winter 2018, LS 3 and LS 4 after Spring 2018, and may need additional classes if they are not finished with the sequence by then.

Will all 3 classes of the 7 series be offered every quarter?

Limited enrollments (classes of 50 students) will be offered starting Fall 2016 as the Core transitions from LS 1/2/3/4 series to the 7 series. Starting Fall 2017, full sections of 360+ students will be offered for the new 7 series

Is it recommended to take the entire 7 series in consecutive quarters?

Yes. The numbering of these courses indicates that they are not considered three separate courses but rather a single integrated course taken over a one-year period. While difficulties with enrollment may pose a challenge, students are recommended to start the 7 series in their freshman year and finish by the end of their sophomore year.

Is it ok to take the 7 series with other science classes within the same quarter or would the workload be extremely heavy?

The workload in the new 7 series is similar to LS 1-4 series in regard to topics covered over the span of the quarter. It is recommended that students exercise the same discretion they currently do when picking courses.

With the previous LS 1/2/3/4 series, you did not necessarily have to take LS1 first. Do the classes in the new 7 series need to be taken in order (A then B then C)?

Yes, the 7 series classes must be taken in order. The numbering of these courses indicates that they are not considered three separate courses but rather a single integrated course taken over a one-year period. In addition, students must complete LS23L in addition to the 7 series. Keep in mind, the previous chemistry prereq that was required for LS 1-4 is no longer required to take the 7 series.

What is LS107? Is it required for my major?

LS107 will review the Mendelian genetics material covered in LS7B and then continue with more advanced topics, most of which are currently being taught in LS4. Each department will have the opportunity to decide if “their” major will require LS107.

Is the 7 series enough biology to cover the requirements for medical school or do I need to take LS107 as well?

Medical schools require one year of biology with equivalent lab. The 7 series will be sufficient in completing this requirement in addition to covering the topics medical schools recommend. Although, for better preparation for medical school, students should consider taking LS107.

Is LS107 required for adequate preparation for the biology sections on the MCAT?

The genetics covered in LS7B and LS7C are sufficient for preparation for the MCAT. LS107 would not be necessary.

Since LS107 is an upper division course, would it count towards my major’s upper division course requirements even if I am not a science major (e.g.: anthropology major but pre-med)?

Check with your specific department to see if the course is acceptable for your major. If it is not, it can still count toward your upper division units required for graduation.

Has any content from the LS 1/2/3/4 series been removed in order to make the changes to the new 7 series?

The only content that has been removed are the advanced topics in genetics currently covered in LS4. Those topics will be available in LS107, a course that will only be required by some LS majors.

Are these changes only happening at UCLA or at other UC campuses as well?

The changes to the LS Core introductory biology series are only occurring at UCLA. The structure of Life Science courses differ across UC’s.

When is it recommended to take LS 23L lab course?

It is recommended that students take LS 23L simultaneously with LS7C. Students must complete LS23L in addition to the 7 series.

I have already taken LS 2, 3, 4, and 23L, but I am unable to take LS 1 this Fall quarter. What are my options if LS 1 will no longer be offered?

If you have completed everything except LS 1 please see the LS Core office to enroll in LS 7B.

What if I fail LS 1 this Fall quarter 2017, but have completed all other series classes. What can I do?

If you have failed LS 1, please see the LS Core office to enroll in LS 7B.

What if I complete LS 3 by the end of Spring, 2018, only. Can I take LS 107 during Summer Session or Fall 2018 to substitute for LS 4 and complete the series?

It has been determined that LS 107 may be taken in place of LS 4 if you are unable to complete LS 4 by the end of Spring 2018.  Please note that LS 107 may only count as either prep for major or as a major requirement, and not as both.

If you are unable to enroll in LS 107 during Fall 2018, please contact our office for assistance.

What if students take Chem 14C/Chemistry 30A concurrently with LS 3, but fail either class. If they fail LS 3 but pass Chemistry, can they take LS 3 and LS 4 concurrently the following quarter? If they fail Chemistry but pass LS 3, can they take Chemistry and LS 4 concurrently the following quarter?

No, students must complete Chem 14C/Chem 30A before taking LS 4.
