I'm about to take the Net+ exam!

in Network+
I'm stressing over this exam! I have until the end of this month to take it. My work pays for the course, but only if I pass the exam! Then if I fail the exam I will be out the cost of the exam too! So I better pass it! I have been studying for nearly 3 weeks straight now. The OSI model is killing me. I can't seem to remeber it and what goes where. Any pointers on the exam as to what should really be studied? I know my week spots like the OSI model that I need to study. Everyone keeps saying the exam is nothing like the study tests they have been taking and that is freaking me out. Any pointers out there?

Good luck
Do you know the following to remember the 7 layers?
All - Application
People - Pressentation
Seem - Session
To - Transport
Need - Network
Data - Data link
Processing - Physical
Sunscreen is measured with an SPF rating... So, In one of my classes years back we used...
S - Segments (transport Layer)
P - Packets (Network Layer)
F - Frames (Data Link Layer)
Burn - Bits (Physical Layer)
Just some quick notes
TCP, UDP, SPX belong to Transport Layer
IP, IPX, ICMP, OSPF, RIP belong to Network Layer
Hardware Address or MAC belong to Data link
FTP, Telnet, HTTP, SMTP belong to Application layer
Equipment:
Routers - Network Layer
Switches and Bridges - Data Link
Hubs/repeaters - Physical, cabling
Hope this is of some help.
For the network+ take as many practice test and read troubleshooting section
greets
keep on
Additionally they have referred to getting odd questions on OC levels and Fiber types/distances.
Good luck!
P.S. You really should understand the OSI model up and down before attempting this test; it's also a popular interview question!
OK... So you know that Routers belong to the network layer of the OSI model.
you know that you can configure IP addresses and IPX addresses on routers. So think of them as network layer the same as a router. The same goes for RIP and OSPF, these protocols can be configured on routers as well.
Honestly it does help a little if you have played with these protocols before on a router.
Ok, I'm afraid of going all over the place with this.... Try to follow if you can.
Think of TCP and UDP as transports for IP... Think of SPX in the same way in regards to IPX.... This at least helps to remember what layers TCP, UDP and SPX belong to.... ANd just remember they are a layer higher than IP and IPX.
Applications.... FTP, telnet and http belong here.... Look at FTP for example... You use it as a program (an application) for file transfers.
I don't know if any of this will be of any help to you, but it's there if you need it.
Good Luck
