Yes the PNAT and the C-net is the same thing. C-NET is the group that administers the P-NAT. I would HIGHLY recommend that you purchase 2 practice tests. One to study from and one to time yourself when you feel like you've gotten everything. The goldwater campus has a prep program every year. Its free and it helps you with everything the test will cover. I HIGHLY recommend you go if you can. Its two days a week and well worth it. Best of luck. And even though the lastest date currently online is the 7th they are eventually going to open up dates going into april so you actually have one of the earlier exam dates.
