It takes some time to get used to a new desktop environment, like Gnome 3. To help you get time to use the Gnome 3 graphical user interface (GUI), you can install the XFCE or LXDE desktop environments as alternatives:
To install XFCE:
# yum groupinstall xfce <enter>
To install LXDE:
# yum groupinstall lxde <enter>
