Prior to taking the PE exam for licensure, you need to take the FE(Fundamentals of Engineering) exam. This exam consists of 2 4 hour sections, the first being a general engineering exam (statics, thermodynamics, intro physics questions, basic circuit analysis, some chemistry/bio, economics, etc) and the second section being a specialization( electrical, civil, mechanical, etc.). I did not take a course for review but instead spent a month or two reviewing questions and taking practice exams. The PE exam is taken much later, after you get several years of experience in an engineering position. For an Engineering Technology degree, that would be 6 years. Read this site(
NYS Professional Engineering:License Requirements) for more information on the requirements. If you are not confident in your background knowledge, there are review courses offered at most colleges to prepare you for the FE exam. I would focus on that for now.
