Almost every paper of ACCA can be done through self study and with group study as well... depends on whether u prefer self study or group study....
I prefer group study because i love to explain the concepts i understand during my studies to others... it can be a <b>good cost saver</b> as well... when i attempted F6(UK), i was the only one among my group (5 people) who took the tuition classes for F6 and i used to teach them whatever i had studied in the class, the very next day... Each of us passed F6 in first attempt and scored very well.
