University Graduation Requirements

Admission

Admission Policies

Minimum GPA Requirement: 2.50

Prospective biology majors with a GPA less than 2.50, but at least 2.0, may be admitted on probationary status. A student placed on probation must meet with an advisor to design and agree upon a probationary course of study based on the student’s previous progress and on established degree program requirements. This course of study must include at least 15 credits that apply toward a degree in the major, with a majority of the credits coming from courses in the college, unless all requirements within the college have been completed by the student. The advisor will place a memorandum outlining the course of study in the student’s file. Students are expected to complete the probationary course of study within two consecutive semesters and one summer. Students who complete the probationary course of study within the allotted time with a cumulative GPA (for the course of study only) of at least 2.00 will be removed from probation.

Biological Sciences Major:

Course requirements:
Biological Sciences majors must complete a set of required 100-level science, math, and composition classes with a satisfactory grade before they can enroll in more advanced 300- and 400-level biology classes. In the first two semesters the typical student will complete the seven biology, chemistry, math, and composition courses listed below with a C or better (C- is not sufficient) as a prerequisite for enrollment in any upper division biology course. These courses, which satisfy university and science major requirements (25 credits), are typically taken in the freshman year:

  and   
  and   
  or higher
  and  

With satisfactory completion of these classes (“C” or better in each class), students will be able to enroll in 300- and 400-level biology classes, subject to any additional prerequisites listed in the course catalog.

If a student does not earn a “C” or better the first time they take a required course, it is expected that they will repeat the course one time and utilize available resources to improve their academic performance. Continuation as a biology major requires a C or better (C- is not sufficient) in each course (or equivalent transferred from another institution).

Transfer Policies

Transfer students must have a minimum GPA of 2.50. All students are required to meet with an advisor to determine course work that can be used to satisfy degree requirements. Biology, chemistry, physics and math transfer courses will be accepted to fill specific degree requirements only with a grade of C or better.
Although rare, it is possible for superior pre-professional students to gain admission to a professional school upon completion of 94 units of undergraduate work. Such students may, under certain circumstances, be awarded a baccalaureate degree from UNLV upon successfully completing one year of full-time study with courses equivalent to the School of Life Sciences major at the professional school. To apply for a degree after one year of professional school, students must have completed 94 units at UNLV with a GPA of 3.50 and meet university and college graduation requirements. Any student contemplating such a program must obtain approval from the departmental chair and college dean in advance of departure from UNLV.

Community College Articulation

The School of Life Sciences has course articulation agreements with several community colleges both within and outside Nevada. For specific information about transfer of credits from two-year institutions, students should seek advising about specific courses of study from the department.

Department Policies

Academic Policies:

In addition to the General Education Core requirements, all study courses must include a minimum of 39 credits in the Biological Sciences and satisfy the specific requirements of one of the five concentration areas offered by the department.

In accord with UNLV requirements, at least 40 credits must be earned in upper-division-level courses. This requirement may be satisfied by selecting courses within and outside the School of Life Sciences.

To graduate with a degree in the biological sciences, a GPA of at least 2.00 must be maintained for all courses in the major field (BIOL). All BIOL core courses taken (BIOL 196, 197, 300 or 304, 351, and 415) must be passed with a grade of C- or better to fulfill prerequisites for other upper-division courses and to apply to the B.S. degree in Biological Sciences.

BIOL 100, 104, 109, 113, 189, 120, 121, 122, 148, 208, 220, 223, and 224 are designed for non-biology majors and do not fulfill the School of Life Sciences curricular requirements. Although these credits will apply to the general university total credit requirement; or might be required or advised for other programs or career tracks (e.g., primary or secondary teaching), they are not recommended for Biological Sciences majors and do not fulfill any requirements for the biology major. The faculty of the School of Life Sciences urge all new majors in the department to enroll in and promptly complete fundamental course work, which will serve as a foundation for success in the study of the life sciences. By the end of the second full year of study (or its equivalent), Biological Sciences Instructors will expect that Biological Sciences majors in all concentrations will have completed: ENG 101 and 102; MATH 127, 128 or MATH 181; CHEM 121 and 122; and PHYS 151/151L and 152/152L (or the equivalent from the PHYS 180 series). BIOL course content will reflect these expectations.

Advisement

All pre-majors and majors in the School of Life Sciences are required to meet with an advisor once a year at the College Advising Center located in Paul McDermott Physical Education Building. Students who fail to meet with an advisor will not be able to register for courses in the fall semesters.

Note

Requirements for the major have been revised. The new requirements apply to biology majors in the class of Fall 2014 and later. Students in prior classes follow the requirements that were in place when they entered the program. Students needing help in bridging gaps between old and new programs should contact the School of Life Sciences office (WHI 101).
