Monmouth Regional High School Precalculus Honors Summer Review This summer review consists of math problems that your teacher will expect you to know entering next year’s Precalculus Honors class. All work must be completed on separate sheets of paper (show all of your work), and your answers should be recorded on the included answer sheet. This packet will be collected at the beginning of next school year.
