- ScantRon forms for exams


Labs:
Students will participate in at least 15 experiments during this course, each designed to investigate concepts covered in the lectures. Individual lab instructors will provide more information on lab grading policies and guidelines.

Tests:
A midterm and final exam will be given during this course. All tests will be given in class.





Grades:
Course averages will be calculated as follows:
Term 1 7%
Midterm 7 %
Term 2 7%
Homework Assignments 5 %
Lab Reports 14%


Final Exam 60 %
Subject Theory : 40 %
