they send out a convocation letter to the PA a month in advance .. so yes, you will have time to prepare .. now, if and when you do get the letter, order GCMS notes right away so you can read the notes made on your file by the reviewing officer .. it gives you an idea of what they found out in your file .. that gives you some hints to prepare at least .. there are questions that previous PAs have been asked .. you can find these questions in our spreadsheet .. there is a link in my signature below ..
