                                   4. TESTS AND EXAMS
(a) There will be a short test at the end of each tutorial. This test will cover the work done during
     the preceding week and the tutorial.
(b) The semester test takes place during the test week at the end of the third term (7th week). This
     test is compulsory.
(c) There is one optional test (valskermtest) during the 4th term. This test is especially for those
     students who at that stage do not have an average mark of 40% for admission to the exam.
     The average of the optional test and the testweek test will be used in calculating the
     classmark.
(d) All tests will contribute towards the classmark.
(e) The examination will consist of a 3 hour paper which will cover all the work done in the
    course.
(f) Non-programmable calculators – as prescribed for the first semester – may be used in tests
    and examinations.
(g) Tests and examinations will be of the closed book format.
                                        5. TUTORIALS
(a) Every week students will receive a set of problems during the tutorial. These problems are
    based on the work done in the class during the preceding week.
(b) Students will get approximately 2 hours to work on these problems. The lecturer and 2
    student assistants will be present to answer questions.
(c) At the end of the tutorial a short test on a similar problem will be given.
(d) The solution of the tutorial test and most of the tutorial problems will be handed out at the
    end of the tutorial.
(e) Attendance at all tutorials is compulsory –also for students repeating the subject. Leave of
    absence will only be granted on the presentation of a medical certificate or written
    permission from the Registrar.
(f)   The textbook, class notes and a pocket calculator should always be brougt to the tutorial.


                                          6. GENERAL
                                          STUDY HINTS
(a) Do regular revision of the work done during the lectures. Homework problems will be given
    on a regular basis. Although these problems are not examined, it is in the students interest to
    do and understand these problems. If you do not understand the work, do not hesistate to
    contact your lecturer.
(b) Do not fall behind. Each week the work builds on that of the previous week.
                               PEOPLE REPEATING THE COURSE
      Students repeating the subject and who have timetable clashes, should contact their lecturer.
      All students repeating the subject are compelled to write the weekly tutorialtest.
                                         PREREQUISITES
      The following two prerequisites (PP  40 ) are applicable:
      Engineering Mathematics 115 and Applied Mathematics B124.
