GRADING

THE GRADE FOR THE COURSE WILL BE BASED 60% ON THE EXAMS and 40% ON THE DESIGN PROJECT. Participation in course discussions will be taken into consideration.

HOMEWORK

PLACE ALL OF THE ASSIGNED AUTHOR’s EXAMPLES AND SOLVED PROBLEMS INTO A THREE-RING NOTEBOOK. Instructor will ask you to submit several of those problems -- randomly chosen -- for grading at each exam.

EXAMS AND FINAL PROJECT

THERE WILL BE SEVEN (7) EXAMS, AND ONE DESIGN PROJECT, which will involve the use of computer program solvers (e.g., Mathematica, MathCad, ANSYS). To ensure fairness in your evaluation, the lowest exam score will be dropped.
