If you would like more information, or if you wish to sign up for an Andrew Wood Acting Studio workshop, the first step would be to contact Andrew at email@example.com and arrange to meet for coffee. This meeting is an opportunity for Andrew to tell you about the nature and workings of the class in full.
Classes meet weekly in the evenings and can sometimes fill up weeks or sometimes months in advance, so signing “as soon as possible” is not a bad idea, to be sure of securing a slot.
There is a fair amount of reading to do for the first day of class, so ideally, you would give yourself at least two weeks time to comfortably find that material and get it read. It’s possible to register closer to the start date than that; doing so will simply mean a bit of a hustle to be ready to start, but it has been done successfully many times.
