Midterm Exam Study Guide

General Guidelines

The exam is taken from Non-Programmer's Tutorial for Python 3 , Python worksheets, and Chapters 1-3.3 of Big Java 4^th Edition by Horstmann. The text, worksheets, quizzes, and programming assignments should be the primary instruments of study to prepare for the exam. The PowerPoint slides in CougarView should be regarded as a companion to rather than substitute for the text. The learning aids in each chapter and the resources in WileyPLUS are also useful in preparing for the exam.
