BACS 371 Test #2 Study Hints Sheet Test 2 will be held on Thursday April 2nd in the normal classroom. The test is over textbook reading, supplemental reading, handouts, lecture, homework, and lab assignments. You will have the full 75 minutes to complete the exam. Bring two pencils and an eraser for the test. You may also bring a single 3 ½ by 5 inch index card with handwritten notes. You may not use any technology to miniaturize your notes onto this card. Cards are subject to inspection and will be confiscated if they do not meet these criteria. You will not be allowed to use your books or any notes in any format other than this single index card. Technical information needed to answer the questions will be provided by the instructor as part of the test. I assume that you have attended class, read the textbook and supplemental readings, and done the homework / labs. What is given below is for extra study emphasis. In other words, you may be asked questions not specifically mentioned below. Good Luck! General: Know the terms covered in the chapters Know the key principles covered in the chapters.
