It takes time to study for a comprehensive mathematics exam; time to review your notes, time to practice a wide variety of problems, and time before and after school to ask for extra help! If you’re only starting to review a week before an exam, you should prepare to set aside several hours each and every day (especially on the weekend).
There will be no direct questions on the Pre-Calculus unit, although everything we learned in that unit has been used to varying degrees throughout the course (linear functions, graphing, exponential and logarithmic functions, trigonometric functions, etc.). There will be no questions involving Integral Calculus on the final exam.
