In 1979, Agriculture and Home Economics periods were further reduced to four hours a week. A change in the Mathematics curriculum was also implemented with the replacement of the traditional Mathematics courses with Math I (Modern Math), Math II (First Course in Algebra), Math III (Geometry), Math IV-A (Second Course in Algebra, part I), Math IV-B (Second Course in Algebra, part II), Math V (Introduction to Trigonometry), Math VI (Advanced Algebra), and Math VII (Introduction to Statistics). Advanced Mathematics classes have been offered starting school year 1980-81 to students who rate high in the math test of the entrance exam and later qualify in a test given to them.
