Practice Exam 4

Important: Remember to try and learn ALL the material for the exam first. Then, set aside a 2 hour time slot and take the practice exam. Do not use any extra resources, data you need is with the question or on the cover page. Work the exam by yourself - just you, your brain, a calculator, and a pencil.

Note: The cover page with data and formulas has been separated from the practice exam. The real exam will have the cover page attached.
