I've used it for a Network+ class. If I remember it's cheaper to do an online class at a school that requires this than actually buying it for yourself.
It's okay, it has simulations where they put you in a virtual office and you drag and click to hook up switches, routers, monitors etc.
It also simulates you troubleshooting connectivity problems between offices.
The only problem I had with the program is that it doesn't explain anything. So if something is new you gotta figure it out. I guess that's where a course or a textbook would come in handy.
It does include a voucher to take the test though, however. So again taking this through a course through a community college if you can.
Good looking out.
