Boot in graphics mode; start a Terminal window
Until you get good at using Linux commands, it's much easier to boot in graphical mode, and start a Terminal window (Applications/System Tools/Terminal). That way you can use commands to control the system while you still have the full gui available. You can even do things like selecting text in the Terminal window, switching to a gedit window, and using the middle mouse button to paste the text into gedit.
If you want to practice with a "pure" console or you need one because the gui has locked up, you can get one by keying Ctrl-Alt-F3. When you are done, you can go back to graphical mode with Ctrl-Alt-F7.
