Oh there are definitely people that take my study group and also attend the Bootcamp. Different strokes for different folks! I think of the Bootcamp as being dedicated time set aside for those that might not have been able to do the more leisurely preparation that my study group allows. Finances can also be a consideration for many as to whether they could do both or not. While I do believe that my study group is sufficient to prepare most students for the exam, I also believe there is no harm in being as prepared as possible so all options are on the table if people want.
