For NJ:
You need 4 years experience and you can pass the FE or PE in any order. So, you can take PE first if you wanted but you wouldn't get your actual license until you complete all three. Also, NJ has that law test (take home/ open book/ multiple choice).
So its:
4 years experience (need this to sit for PE)
Pass FE Exam
Pass PE Exam
Pass Engineering Law Exam
The main difference here is that its not graduate from school/ pass FE then work experience starts from the one you completed last. Also, I think you can take the Law test as a follow up to the FE. I didn't know about it so they sent it to me with a letter stating I passed the PE.
you might want to check the actual dates. I had 4 years up to the exam date but alittle short if you count to the app deadline. They count experience to the app deadline. I guess it depends on the person reviewing it but you can send it in and if it gets rejected; they will keep it for the next cycle.
Make sure you send in everything early cause they take their sweet time reviewing it. (unless there were alot more applicants then usual). I was calling the office everyday on the last week of the deadline for paying for the actual exam. They had my information 2 months before that (confirmed by them) and they ended up sending me a letter saying that i was "approved" to sit for the exam but my experience, transcripts, etc were not reviewed.
