Congratulations!
Looks like you are on a path similar to mine. I was raised in November of 2016. I attended ONE Stated meeting where I sat on the sidelines. In January of 17 I was asked to fill in the JD chair, in Feb of 2017 I was appointed JD as the previous Brother in that chair bowed out. Over the summer of 2017 the SD had family issues and I was moved to the SD chair and in December of 2017 I was elected JW for the next Masonic Year. There was A LOT to memorize, but with help from several Brothers, the Wardens, WM and PMs, I was able to get signed off at District School as proficient in the Business of the Lodge and the EA Degree as required to stand for election as JW.
I suggest you reach our for assistance in learning the work to whoever is in charge of Masonic Ritual Instruction at your Lodge. You are on a very exciting path for the next several years and I think you will find it both a challenge and very rewarding!
