Messages from the College Board (they bring you  Advanced Placement Exams, etc.)

     “Before studying calculus, all students should complete four years of secondary mathematics designed for college-bound students: courses in which they study algebra, geometry, trigonometry, analytic geometry, and elementary functions.  These functions include those that are linear, polynomial, rational, exponential, logarithmic, trigonometric, inverse trigonometric, and piecewise defined.  In particular, before studying calculus, students must be familiar with the properties of functions, the algebra of functions.”
     What follows are the instructions that students see at the top of the A.P. exams in calculus.

Instructions at the top of Section II: Advanced Placement Calculus Examinations:
       Time------ 1 hour and 30 minutes
       Number of Problems ----  6
       Percent of total grade ----- 50

       SHOW ALL YOUR WORK.  Indicate clearly the methods you use
       because you will be graded on the correctness of your methods as
       well as on the accuracy of your final answers.  If you choose to use
       decimal approximations, your answers should be correct to three decimal
