College Algebra Tutorial 33: Practice Test on Tutorials 25 - 32

Learning Objectives After completing this tutorial, you should be able to: 1. Take a test on topics covered in tutorials 25 - 32 in this website. Note that I can not guarantee you will pass your test after going though any of the tutorials in this website or this practice test. However, it will definitely help you to understand the topics covered better. Disclaimer: WTAMU and Kim Peppard are not responsible for how a student does on any test or any class for any reason including not being able to access the website due to any technology problems.

Introduction It is important to note that, chances, are I'm not your math instructor, who knows you may be one of the lucky ones and have Elvis as your math instructor. You need to check with your math teacher as to things like when your next math test is and what it covers. It may cover more material on the test than what is in this practice test. Just note that there are other practice tests at this website. So, after finding out what is on your test (if you have one) do the practice test(s) problems that go with the test you are preparing for. If you are not in a class or are not having a test soon, this practice test is

still good practice to go through and check to make sure you are understanding this material before moving on - kind of like a spot check. The material on this practice test goes with Tutorial 25: Slope of a Line, Tutorial 26: Equations of Lines, Tutorial 27: Graphing Lines, Tutorial 28: Parallel and Perpendicular Lines, Tutorial 29: Circles, Tutorial 30: Introduction to Functions, Tutorial 31: Graphs of Functions, Part I, Tutorial 32: Graphs of Functions, Part II. Also note that your teacher may word the problems on their test a little differently, may have some different kinds of problems, or may have a different number of problems than what is in this practice test. Again, since I'm probably not your math instructor, I don't know exactly how your teacher will set up your math test. Just note that these problems will help you build an understanding of the concepts presented and the terms used in math problems. If you have an understanding of the problems instead of just memorizing them, then you should do fine on these concepts, no matter how the test is set up.

Steps to Studying for a Math Test 1. Work through problems. If you are in a class, you should have done this on completion of any homework you have done. For anyone, you can accomplish this by doing the practice problems found in each tutorial. 2. Check work on problems. The practice problems in each tutorial have links to the answers to them so you can instantly check how you are doing. Also, in most math books, the odd answers are found in the back of the book. 3. Review concepts. Whether you got the problems right or wrong, make sure you review over them. If you did get a problem wrong, make sure you either review that concept in it's respective tutorial or ask your math teacher about it. If you don't ask about a problem before a test, you are going to kick yourself when it comes up on the test. 4. Work through problems as if you were taking the test - no notes, book, webpages, etc. This practice test is a perfect way to do that. After taking this practice test, check your answers by clicking on the link to the answer key found at the bottom of the practice test (before the 'need extra help on these topics' section)

During the Test It is to your benefit to show as much of the work as possible on the problems that have several steps involved. Make sure that you read the directions carefully, you wouldn't believe how many points get taken off math tests for people not following directions. Pace yourself. You do not have to be the first one done to do well on the test. Do not panic if there is still time left to take the test and others are turning it in. Sometimes that means they do not know the material and left some of the answers blank. Do not worry about anyone else but yourself. Don't rush through a problem. Another thing that math teachers take points off for are careless mistakes made by people that rush through a problem. When those students get their tests back, they bonk themselves on the head at some of the things that got counted wrong, things that they knew how to do. Check your answers. If you have time, go back and check your answers. Remember to breathe!!!! I know some of you are scared to death at the thought of having to take a math test of any kind. For you guys, try to relax and don't forget to breathe. (Even if you aren't scared to take a math test, it is probably a good idea to remember to breathe, I wouldn't want you to pass out during the test) Good luck on your test. If you are taking a math test soon, good luck on it. I know you are going to do great!!!
