I need some pointers for taking the residential plan review certificate test. what to study. I have my combo certificate but looking to add res plan review. How much is this test structured like the ICC's other tests? Is there a lot of question off of plans? Give me some ideas so I dont have to sacrifice the first test so I can study more. Nothing worse than missing a test by 1 question. I did that once and have never had to experiance that again. but I havent taken any of there tests in a while so I'm rusty.
