Let not your heart be troubled. Here is the sequence: You submit your petition to be made a Mason. The lodge does an investigation. The investigation reports to the lodge. Your application is voted on, and if successful, you are invited to attend a degree meeting.
You go to the lodge, take the Entered Apprentice Degree. You will have to memorize a certain portion of what you have experienced. Don't worry, the exam is not hard. You pass the exam. Then you take the Fellow Craft Degree, stand an exam, and then you take the Master Mason degree.
The entire process usually takes about 4-5 months to complete. Then when you are a Master Mason, that is the "black belt" of masonry, there are no higher degrees.
Do not let concerns about the exams frighten you. You will be coached, and no one fails the exams.
If you have decided that Masonry is right for you, then go ahead and ask for a petition, and submit it!
