Adv Alg/Precalculus Problem Sets
4th Quarter
READ THE DIRECTIONS CAREFULLY!
 Problem sets are designed to review concepts taught in previous courses as well as
those taught in this class. Problem sets must be taken seriously and emphasis should
be on the process to answer each question and not necessarily the answer itself.
 Problem sets are due according to the schedule below.
 You may seek help any time before the due date. STUDENTS ARE NOT
ALLOWED TO ASK FOR HELP ON THE DAY IT IS DUE!!! Students must also
have work to show the teacher before asking questions.
 ALL Work must be shown to receive credit. Work done on a separate sheet of
paper must be attached to the actual problem set. Calculations performed on a
calculator must be shown/written on the paper.
 Problem sets WILL NOT be accepted late if you are at school on the due date. If you
are absent on the due date, it is YOUR responsibility to turn in the assignment on the
first day back to school. Absences for school related activities (sports, field trips, club
activities, etc.) DO NOT excuse you from submitting problem sets on the due date.
 All Problem Sets are due at the beginning of class.
 Students must turn in all problem sets and must earn at least a 50% on each in order
to be eligible for grade replacement from the Quarter 4 Assessment.
