COURSE EVALUATION
Student assessment
The assessment shall be based on continuous assessment as well as the final examination. The
continuous assessment shall contribute 40% and the end of semester examination shall contribute
60% of the overall mark. For continuous assessment, at least three tests and three assignments shall
be given which contribute 15% and practical shall contribute 25%.
Every student is required to join the online class as assignments and quiz will be
given using the online classroom.
