Evaluation Scheme:

The final grade is computed according to the following weight distribution: Mid-semester exam (35%), Final exam (40%) and Assignments (25%). Open-book examination is given in both mid-semester and final exams.


 An “A” will be awarded if a student is able to show profound understanding of the principles of irrigation and drainage systems, and is adequately able to apply the knowledge for suggesting management for real problems. A student who is participating and contributing actively in class discussions and assignments would be placed in this category. A “B” will be awarded if a student is able to show satisfactory command over the subject matter and show an overall understanding of all given topics. A “C” will be given if a student is able to show satisfactory command over the subject matter. A “D” will be given if a student displays very limited knowledge of the subject matter, and does not appear motivated to learn new things.
