Hi Daniel,
Well, I'm not at Certificate levels. But just a suggestion that, always be careful when receiving assistance from another fellow student (even who is at the same level as you are). Because, non of you are tutors and in some occasions, you may ASSUME a concept as the correct form, whereas it may have been wrong (wrong concepts may affect long-term studies). Anyways, group study is a fne concept and I wish you all the very best of luck with CBA :)
