Grading Scale: GRADE A AB+ B B-

SCORE RANGE 90 % & up 86 % & up 82 % & up 78 % & up 74 % & up

GRADE C+ C D F

SCORE RANGE 70 % & up 65 % & up 55 % & up Below 55 %

Course Policies: Homework: Homework will be assigned and solutions will be posted, all through an online tutorial system “MasteringEngineering” (See Section F for details). It is very important that you perform the homework on your own before you utilize the solutions to identify your errors. Homework will be selectively collected for grades verification, though grading will be done by MasteringEngineering online. No late homework submission will be accepted for any excuse. Quizzes and Exams: Pop-up quizzes will be given in both regular lecture and problem solving classes. No make-up quiz will be granted for any excuse. Excusable absence from the scheduled exams is accepted only if the student informs the professor before the event such as illness and nonreschedulable prior appointment, or after the event such as last-minute medical or other emergencies, within a reasonable time frame and with a valid documentary proof shown (e.g., medical memo from doctor, letter from employer, etc.). In all cases, academic honesty is expected. Under this condition, a make-up test will be honored. No 4-C Policy: No Cell-phone, Computer (unless taking notes or test), Chatting, or Cheating is allowed or accepted in this class. Learning Strategy: Simply reading the solutions is absolutely the worst strategy for this course. You need to practice as much as possible. Calculators allowed in test (by National Council of Examiners for Engineering and Surveying): Casio: All fx-115 models. Any Casio calculator must contain fx-115 in its model name. Examples of acceptable Casio fx-115 models include (but are not limited to) · fx-115 MS · fx-115 MS Plus · fx-115 MS SR · fx-115 ES Hewlett Packard: The HP 33s and HP 35s models, but no others. Texas Instruments: All TI-30X and TI-36X models. Any Texas Instruments calculator must contain either TI-30X or TI-36X in its model name. Examples of acceptable TI-30X and TI-36X models include (but are not limited to) 3

Academic Misconduct: Florida International University is a community dedicated to generating and imparting knowledge through excellent teaching and research, rigorous and respectful exchange of ideas, and community service. All students should respect the right of others to have an equitable opportunity to learn and honestly to demonstrate the quality of their learning. Therefore, all students are expected to adhere to a standard of academic conduct, which demonstrates respect for themselves, their fellow students, and the educational mission of the University. All students are deemed by the University to understand that if they are found responsible for academic misconduct, they will be subject to the Academic Misconduct procedures and sanctions, as outlined in the Student Handbook. Other: Academic dishonesty is a serious offense and will be treated according to the University policy. The instructor will abide by the University’s policy on religious holidays. G. INFORMATION REGARDING “MasteringEngineering” “MasteringEngineering” is an online tutorial and homework system that accompanies the textbook listed above in Section A. All homework will be assigned and graded through this system for this course. As a student to register and access this online system, you need to have: 1. A valid e-mail address (Please register with the email address that you check regularly) 2. Course ID: MESUN29955 3. A valid online access code (provided by publisher as you purchase the textbook)
