hey guys so I have been an installer for 13 years. Ive done almost everything there is to do in the field with the exception of das and AV rack work ive just never had to do it. I just started studying for my RCDD exam. I spent 8 years in the field and the last 5 have been in a data center and its crazy to see how much I don't know when it comes to how the things ive build for so long actually function. Im stuck on chapter one trying to memorize all the terminology. I feel like im spending too much time on it. however I want to make sure I am retaining what im reading. im scoring like 65-70 on the quizzes for Cory and Steve im doing a little better on the ones on quizlet. Anyone have recommendations should I just move on and circle back? what's most of the RCDD based on? Do they actually expect you to memorize the sinusoidal signal formula ?

I have been using Zyn for about 3 years . I have been having headaches for the last 6-7 months. its not a regular headache though its across my forehead slightly above my eyebrows. I guess that's where your sinuses are I was wondering if anyone else had a similar experience. Its miserable im down to about 7 3 mg pouches a day I think im going to try to quit in the next week I don't know if its the cause but it makes the headaches worse and I figure by quitting ill find out if its the main root of the issue im having. I appreciate any feedback
