In order to pass the examination a student must receive a passing grade on a total of seven questions, with not less than three passing grads in each Part.
Students may elect to take the Written Preliminary Ph.D. Major Field Examination to satisfy the comprehensive examination requirement in the program leading to the Master of Science in Civil Engineering (Plan II).
Studentsare permitted only two (2) attempts at passing the Written Preliminary Ph.D. Major Field Examination, including any attempts made to satisfy the M.S. comprehensive examination requirements using this examination.
