I am about to take NC 4 again on 4-28. I failed this one last summer and have put it off until just about my last test. If I do not pass this time, I will not be able to take it for 4 more months. Any tips/advice???? I am really nervous and am not used to failing grades. What is the most important part of this test. By the way, I am using Chancellors study guides for my tests.
