Help with paket tracer Static routing

[bradyrogers11]

Hi everyone I'm studying to be a network admin at my local tech college. Today I had my midterm and a part of the test was to configure static routing from scratch with 5 routers and 2pcs at each end which are able to ping each other. My issue is the pc's can't ping each other and I don't know why and I don't want to wait 5 days before I can ask my instructor where I went wrong. 

Attached is my packet tracer test, Please let me know why the pc's cant ping each other and how I could fix it! Please and Thank you!

Hello,

After looking at your PT file you have some fluff and the routes don't match up.

For the main issue all your interfaces are a /14 but all your static routes go to /24. For example:

ip route 12.100.1.0 255.255.255.0 -> interface is 12.100.1.10 255.252.0.0

Change all your router interfaces to a /24 mask. Also make sure you change your PC masks to /24 as well. 

Then on R4 you have several varying routes to the 12.100.1.0 network with different masks. You can remove those as R4 is aware of its locally connected networks.

In a few other places you have the ip route 12.100.1.10 255.255.255.255 - this is not needed. I assume you put this to force all your routers to get that IP to make the ping work. You just need the ip route 12.100.1.0 255.255.255.0 route on all routers (except R4) using the exit interface towards R4.

Hope that helps
