You are correct, the questions that you will see are taken from a large set and each one is generally different. So relying on what I or anyone tells you about how much of each topic was on my test doesn't really help you. The FAA has published the different topic areas that you need to understand and the test will cover each in various levels of detail. There will definitely be questions on sectionals (maps) and weather, but how many of each varies a lot. Murphy's Law would tell you that your test would probably have a lot of questions on any area that you tried to skim by on! Pull up some of the suggested material and look it over. If it looks totally foreign to you and you aren't a really disciplined student, consider taking an online course. Anyone can do it on their own, but you have to work hard at it. And remember, if you fail the first time, you have to pay the $150 again to retake the test!
