Using this online redox tutorial and practice problems - A User Guide from Yue-Ling Wong

Best viewing: Many of the online tutorial and practice on these web pages could take up the whole screen. To view as much of the content as possible so you don't need to scroll the page too much, try to maximize the Netscape window, turn off the Directory Buttons, Show Main Toolbar as either Picture or Text only, 16-bit color display mode.
Online Notes-taking: The tiny Online Jotpad on the left pane lets you take your own notes online while you are going through the online tutorials. You can save your own notes by clicking on the tiny Save button at the upper righthand corner of the Jotpad. When you do so, it will save a copy of your notes onto your hard drive. Next time when you start this tutorial again, you will see your notes showing up in this Online Jotpad.
Q1: How can I find my notes saved on the hard drive?
Click on the Start button at the lower left corner of your screen, choose Find, and Find Files or Folders, type in redoxnot.txt, and click OK.
Q2: Can I read and edit my notes without going to this redox web pages?
Yes. Find the redoxnot.txt as described above, and double-click on the redoxnot.txt found. It will open as a text file. You can read and edit your notes there.
Q3: If you are using computer lab computers...
If you are not using your own computer or ThinkPad, you probably don't want to save your notes. However, you can still take notes during the tutorial; just don't hit the Save button at the upper-right corner of the Jotpad. It won't save your notes. Your notes stays on the Jotpad until you exit Netscape or leave these redox web pages.
Interactive Tutorials: Most of the online tutorials here will ask you to enter answers in some steps. Although you can skip answering the questions most of the time, you are encouraged to enter the answers and have the answers checked during the tutorial.
Interactive Practice Problems: Questions are randomly generated from the question sets written by Angela King. You can continue doing the Practice Problems until you have got all the available questions correct. You get points for correct answers. If you get it wrong, the question may appear again if you continue. Your instructor will NOT know nor keep your scores for the online Practice Problems.
In the Assigning Oxidation Numbers Practice Problems, if you get all three questions in the same set correct, you will see a little surprise. Make sure you turn up your speakers!
