So I recently posted on Twitter that the formulas for the Extra class exam was kind of making me feel stupid because it’s been so long since I did any kind of serious math. I got a couple replies saying I didn’t need a calculator for the Extra Class test. Well, since they pull from a group of questions where all the questions and answers are known, yeah.That’s just raw memorization and reciting the answer on command. That’s not what I want to do. I want to understand the theory and use it in a practical purpose in my own projects. If someone else wants to pass the test to say “Yeah, I have an Extra Class”, then feel free. I believe that knowing this theory and being able to use it in a practical sense make someone a m0re rounded Ham and able to tackle new problems and take on more complex projects.

Now Yes, there are times when you just need a shortcut for the math. It makes it easier. So here are 2 videos that kind of show you what I mean. These make it a little easier for me to grasp the math behind the theory. If you’re studying like me, good luck!
