Routing and subnetting

I am having trouble understanding subnetting in routing.
Now I have the exam, and I can't figure out which subnet is causing trouble in a network, and how to change the network ID and subnetmask to make it work.
Anyone that can help?
I'd appreciate it.

The easiest way to understand subnetting is to google the "magic Number" Danscourses.com has some free youtube videos available.
As far as routing goes I just write out the range and see if it fits.“The Only way to do great work is to love what you do. If you haven't found it keep looking. Don't settle” - Steve Jobs -

I'm watching Danscourses right now actually. But I'll try your tip. Thanx!goldenlight wrote: »The easiest way to understand subnetting is to google the "magic Number" Danscourses.com has some free youtube videos available.

Nah, hard to understand. I have a drawing, maybe someone can help explain a little what is wrong here?

All looks fine with the exception of the bottom subnet.
192.168.1.64 - 192.168.1.127
192.168.1.128 - 192.168.1.191
192.168.1.160 - 192.168.1.175
192.168.1.208 - 192.168.1.223
192.168.1.244 - 192.168.1.245
192.168.1.248 - 192.168.1.249
This is where the overlap occurs. This is were packets will fail/loop depending on the routing protocol in use.[CCENT]->[CCNA]->[CCNP-ROUTE]->COLOR=#0000ff]CCNP SWITCH[/COLOR->[CCNP-TSHOOT]
