    Note: These are group projects BUT grading individually *write who do what in what%?*
    Grading: (tentative)
    Mid-Term Exam (Lecture) + Industrial Exam25% +/- 25%
    Final Exam (Lecture/Lab)30% +/- 20%
    Homework + Lab + LabHW + Quiz + Class participation25% +/- 10%
    Security Tools/App20% +/- 10% (grading individually)

    Note that students are allowed to bring only "ONE" piece of A4 paper in midterm/final exams with additional non-memorized calculator
    The final exam material will be after the mid-term; however, all related contents will be also covered.
    The exam includes 1. True/False (+1, -1, and 0), 2. Numerical and Analysis, and 3. Fill in the blank.
    The final grade will be curved based on the overall performance of the whole class (probablistic clear cut-off point).
    Note: Extra Credits:
  • +2.5 to 5% = 1st round competition
  • +5 to 10% = Final round competition; Published Paper/NSC/Imagine Cup/Samart etc.
  • +5 to 10% = Published Paper (networking etc.)
  • +1% = Taking a security contest exam
  • +1 to 2% = Taking/passing the security online course, e.g., udemy and coursera
  • +5 to 10% = Passing Security Certifications
