CCNA 1 and 2 are not give us practice skills. Packet Tracer is not the real world. The students have no idea how to setup the rooter, switch and other devices. The teachers don't know how to teach and they do what they want. There are not any control on teachers. How do students learn to install a network if the teachers almost are sitting on their chairs in business and watching football on laptop? After I finished CCNA 1 and 2 my network skills are nothing. Sometimes I think that Cisco has no idea about the real academy world.
