What more would you like to learn?

There were many unknown things for me about computers, and through attending this course, I feel more familiar about them than before. However, there are still what I want to know, that is, how to use Excel. It is very hard for me to calculate by Excel. I have to type the formula. The other day I wanted to sum 23 different numbers up; however, to finish this, I spent a long time, which I could calculate them by myself. Thus, I wanted to learn it in the class; nevertheless, I have the best home page, Poza.net/sp07!!! Therefore, I do not need to worry about it! I may be able to understand how to use Excel by looking at the site! I must say thank you for creating always-available and virtual textbook to Mr. Poza.
