How to Succeed in Precalculus
Understanding Math is Within Your Abilities...(really!)
Here are some suggestions for finding how capable you really are:


Be Prepared for Class Discussions
Have your homework completed on the day it is due.  This is vital to being a successful math student.  The teacher assumes that each student has completed the assignment before coming to class.  When you've done the assignment, you are aware of what you know and even what you don't know.  If you find your attention tends to wander even during one of my captivating lectures, then you might consider printing out notebook organizersfor the sections.  
These notebook organizers are designed to help students organize their notes, and provide section-by-section summaries of key topics and other helpful study tools.

Know Thyself
The purpose of assignments is to help students master the course objectives.  Mastery of those objectives will be indicated by your performance on the quizzes and exams.  Thus, the homework is meant to prepare you for those exams.  That said, keep track of your challenges.  If your answer didn't match the answer in the back of the book, if you asked a friend or the teacher for help, or if you use some of the resources below in order to understand a problem,   After an hour has passed, go back to those troublesome problems and see if you really do remember how to answer the questions.

Check your answers as you go
When you are working on your homework, keep a bookmark or your finger in the back of the text so that you can check if your answer is correct each time you answer an odd-numbered question.  Some students are inclined to wait until after they have completed an entire section of homework before they check for correctness. The problem with this method is of course the lack of motivation you will have to go back and determine how you went wrong with perhaps a significant number of problems.

Some Worked-Out Solutions are Online
The publisher of your book has put together a web site that provides you with a glimpse of the worked-out solutions to the odd-numbered problems.  Note the title of your book is Precalculus with Limits a Graphing Approach 5th Edition.  Also, you will needMacromedia Shockwaveinstalled in your browser.  Click hereto go to the online solution site.  I think you will find this site quite helpful.  The solutions are given without any annotation or explanation.  I expect there will be times you will need help interpreting a work-out solution.  What's a student to do?  Read on...

There are homework help sites that are available too.  For example, www.calcchat.comoffers an 18-month subscription service for $25.  I cannot write a first-hand account of the site nor state my thoughts on the value of the subscription, I merely mention it as another option.

Make Certain You Know the Material
Test your understanding by answering the questions at this site: Practice Multiple choice Questions.

Make an Appointment with your Teacher
I'll stay after school until 4pm to help you to understand the stuff that is confusing you.  Please let me know when you plan on staying after school for help.
