Placement Exam

All students must take the placement exam during Orientation week. The results of the placement exam are used to advise students which track to pursue.

Courses of Instruction

Pre-engineering students should refer to the First Year–Sophomore Program to determine the chemistry requirements for admission to particular Junior-Senior Programs. Special attention should be given to the requirements for admission to chemical engineering, biomedical engineering, materials science and metallurgical engineering, and other related fields.

Laboratory Fee

The laboratory fee covers the cost of nonreturnable items, chemicals, and reasonable breakage. In addition, students may be charged for lab handouts and excessive breakage, for cleaning of equipment returned dirty, and for checking out late.
