I'm not sure if it's the same for all magic society's but I wouldn't wait to plan a routine before joining as generally you will find that you have to wait several months anyway before you can audition.
Most Society's have a busy schedule and have to plan their lecture nights months, and sometimes over a year in advance. With other club activities you may find that you only get the chance of an audition night three or perhaps four times each year.
Generally, they're quite happy for you to go along for a couple of meetings and then pay your membership to join as an associate. You will then get your audition date later on which gives you plenty of time to plan ahead.
You may well find that you get the opportunity to sit through an audition night and watch others and this will be a great help to you and your planning.

It's not really an optical illusion - it just looks like one!
