Yes. LS 1a and LPS A fulfill the requirement for one semester of general chemistry with laboratory. LS1b fulfills the requirement for one semester of biology with laboratory.
Absolutely not. The courses are open to everyone, although students who are considering concentrating in one of the Life Sciences are strongly encouraged to take them in their first year.
Both LS 1a/LPS A and LS 1b are required for concentrators in the following seven Life Sciences concentrations:
Biomedical Engineering
Chemical and Physical Biology
Human Developmental and Regenerative Biology
Human Evolutionary Biology
Integrative Biology/Organismic and Evolutionary Biology
Molecular and Cellular Biology
Neurobiology
The Cognitive Neuroscience and Evolutionary Biology track in Psychology requires one of LS 1a, LPS A, or LS 1b. The Chemistry concentration requires two of the following: LS 1a,...
Yes, hundreds of students take both LS 1b and a physical sciences course, such as Physical Sciences 1 or Physical Sciences 11, during spring of their freshman year. For help with choosing your spring semester courses, we encourage you to talk with any of the Life Sciences advisors.
After the first semester, all students choose from the same set of courses. Most life sciences concentrators – regardless of whether they took LS 1a or LPS A – choose from among LS 1b, Physical Sciences 1, and Physical Sciences 11 in the spring semester of the freshman year.
If you have little or no science background, you should consider taking Life and Physical Sciences A (LPS A) in the fall. You should take the on-line chemistry and biology placement exams for course recommendations. Based on the results of the placement exams, you will receive a recommendation for your fall course.
Yes. Even if you have a strong high school background, these courses will provide new approaches to material that you will not have seen before, and the courses will prepare you for advanced Harvard courses more effectively than relying on your high school preparation alone.
Life Sciences 1a (LS 1a) and Life Sciences 1b (LS 1b) were designed as the foundation for the life sciences concentrations. Based on your background preparation, Life and Physical Sciences A (LPS A) may serve as an alternative to LS 1a. The fall semester courses, LS 1a and LPS A, introduce chemistry, molecular biology, and cell biology. LS 1b, which is offered in the spring, covers topics in genetics, genomics, and evolution.
For course advice, you should take the biology and chemistry placement exams. Based on the results of the placement exams, you will receive a recommendation for your fall course – either LS 1a or LPS A. If you are unsure of which course to take, you should talk with a life sciences advisor. A team of life sciences advisors will be available to talk with you at the Science Advising Session in the Science Center during Opening Days.
Both LS 1a and LPS A are offered in the fall and are introductory courses in biology and chemistry. LS 1a integrates chemical and biological principles throughout the semester, and also applies these concepts to larger biological problems such as HIV and cancer. LPS A is aimed at students who, based on their background in chemistry or biology, require additional preparation before taking further science courses at Harvard. In LPS A, the first half of the semester is devoted to a study of general chemistry, and the second half of the semester explores molecular and...
All students are welcome in these courses, whether or not they proceed to more advanced work in the Life Sciences. First-year students who are interested in concentrating in any of the Life Sciences should take these courses. Students who wish to satisfy pre-medical requirements, but are not thinking of concentrating in one of the Life Sciences, are also encouraged to take these courses. For more information, please consult the OCS website.
