You need to have the degree requirements in order to be considered for an NJ PLS. The grace period to get a license without a degree ended better than 15 or 20 years ago. If you have a Civil degree, the NJIT program is perfect for you. It's exactly what I did. I think it was 12 classes I had to take and then with that degree was accepted to sit for the exam. By the time I finished my degree, I already had my PLS in PA and Ohio, so all I needed to take was the State Specific Exam and Law exam.
The reason the checklist says not applicable is because there is no way you could have taken it unless you were already approved to site for the NJ PLS exam. I always found it ironic that they had that on the application.
As for resources, I don't remember where I got it, but I have a reference manual prepared by Robert Ent, Jr. from May 2006. It's 750 pages and 19mb, but definitely helpful as a study guide. I'm certain that if you can't find it, we can figure out a way for me to get it to you But as I said, if you don't have a surveying degree the Board won't even look at your application.
