Passing Mark is 50%. 54 Homework: Homework assignments are due at the beginning of class. Homework that is turned in late will not be accepted. Any schedule adjustments will be announced in class. One problem per page, front side only, with the final answer clearly defined. Work that is disorganized or incomplete will not be graded or will receive a lower grade. You must display all of your work, not just the finished result. Students should never duplicate from another source, nor should they allow others to copy their work. Exams/Quizzes: There will be at least three main examinations, which will most likely correspond with the three major examination periods established by the University Registrar. Unannounced quizzes will be administered to help measure the student's progress. The major exam dates are shown here; however, all dates are subject to change. Any modifications to the schedule will be announced in class. If a student must skip an exam for good reason (e.g., illness, family emergency), he or she must notify the instructor prior to the exam date. A message can be left with the instructor at any time by phone, email, or short desk notice. Except for confirmed illness or family crises, there will be no make-up exams. Special exams may be offered for a justifiable reason and must be completed within three days. Final Answer: For exams, students are expected to provide clear, concise, and complete answers that demonstrate their understanding of the course material. It is important for students to show their work, if required, including any formulas, calculations, or steps taken to arrive at the final answer. They should also be aware of the time limits and manage their time effectively to complete the exam within the given time frame. It is also important that students refrain from cheating or any other academic misconduct, during the exam they should not use unauthorized resources, or communicate with others during the exam. It is also expected that students to bring any necessary materials such as calculator, etc.The final answer is crucial, but so are the underlying principles and solution techniques. However, because of a "minor" error, the student should not expect significant partial credit (s). Students are encouraged to double-check their assignments. Partial Credit & Review of Exam Grades: If a student believes he or she is entitled to extra partial credit for an exam difficulty, he or she should visit the instructor during office hours and submit a case for adjusting the grade. Exam marks should not be erased. Students should clearly demonstrate where a mistake occurred and how it affected their solution. To help the instructor fairly assess the exam, the student should endeavor to show what was correct on the exam and describe the method utilized on the exam. The work exhibited on the exam and accomplished throughout the exam session must be graded by the instructor. Students are urged to offer their best explanation of what they did during the exam in order to receive the highest possible grade, but they must accept the instructor's decision. Start and finish with a pleasant mindset. All reviews of exam grades must be completed within 24 hours of the exam being returned to the student and within two weeks of the exam being returned to the class. Class Conduct: Students are expected to conduct themselves in a professional and responsible manner while in class. This includes being punctual, actively participating in class discussions and activities, and following all safety guidelines. They are expected to show respect to their classmates and instructors at all times and refrain from disruptive behavior. Additionally, students should be prepared for class and come equipped with necessary materials such as books, notes, and any other equipment required for the class. They should also refrain from using electronic devices or engaging in other activities that would distract themselves or others unless instructed otherwise. It is important for students to maintain a positive learning environment for everyone in the class. Scholastic Dishonesty: Scholastic dishonesty is strictly prohibited and will result in disciplinary action, including but not limited to, unauthorized collaboration, plagiarism, fabrication, or cheating on exams or assignments. Students found guilty of such conduct will face consequences such as failing the assignment, or even failing the course. It is expected that students will be honest in their academic work and will not engage in any form of academic misconduct. Withdrawing from the Course Please make yourself aware of the Registrar’s dates and policies about withdrawing from a course or withdrawing from the Institute. If you fall behind, don’t just give-up and quit attending. Contact the instructor or your course adviser and explore your options. If you drop the course, double-check to make sure it is done properly. Habitual and excessive absences will be reported to the Department Chairperson, College Dean, and/or Guidance.
