Cheating cases (assignments/codes/exams/project) will be dealt with in accordance with the Institute norms. It is expected that everyone will uphold the honor code.

All delays beyond the defined deadlines will attract reduction in marks as per the following curve. The reduction factor, \(R\) will be multiplied to the obtained marks. Mathematically, it is given by: \(R = \exp(-D^2)\), where \(D\) is the total delay in days (will be counted hourly, i.e. fractional days are possible).

Following will be the weightage of different components of assessment

• Tutorials will involve two types of problems:
  • Set A: to be submitted within the tutorial hour and will be graded towards Tutorial weightage
  • Set B: to be practiced outside the tutorial hour and will not be graded
• Assignments will entail analysis/design problems, practical problems, visit reports, etc.
• Exams will involve take home type analysis/design problems along with viva/presentations.
• Expect one assignment and tutorial per week.
• In-class submissions will comprise of small problems to be solved in-class (in groups).

It is important to develop the habit of self-learning. A number of reading assignments and self-exercises will be given during the course. These will not be formally graded and it will be expected that students will go through them on a regular basis on their own.
