**Physics in the Sciences and Letters Curriculum (BSLAS)** allows students maximum flexibility to develop scientifically oriented careers in fields requiring a physics background through the Major in Physics or the Physics Teaching Concentration.

The Major in Physics is a flexible program for students who plan to pursue technical or professional careers in areas requiring a sound grounding in physical science and mathematics. Students can use the concentration to prepare for employment immediately upon graduation or for continuing on to graduate study in a wide variety of fields.

The Physics Teaching Concentration fulfills state certification requirements to teach both physics and general science.

**LAS Specialized Curriculum in Physics (BS)** is designed for students who plan to pursue graduate study in physics or a closely allied field. In some cases, however, the greater flexibility of the Science and Letters Curriculum may make it a better choice for graduate school preparation for those who want to pursue a combined major and minor, a double major, or double degrees.

See also Engineering Physics in the College of Engineering. See the Physics Department for additional information.
