Proportion of final grade and Probable date Term test 20 % last week of October Lab test 12 % end of November Lab reports 18% as assigned Final exam 50% to be announced ______________________________________________________________________________ Policy with regards to term tests and laboratory: Any student missing a test will be assigned a grade of zero unless a doctor's certificate or a valid justification is received within one week of the test. Students who cannot write a test for non-emergency reasons must get permission from the instructor, prior to the test. In any case, the final exam will be on 50% plus the value of the missed test. No individual “make-up” tests will be given. Laboratory attendance is mandatory (check rules on your lab outlines). A passing laboratory grade (50% or higher) is required in order to pass the course. Evaluative feedback on the term test will be given prior to the voluntary withdrawal deadline.
