ACCA Dec Exam 's Result published

Finally, the result for my three papers from F1 till F3 have been announced on 16.2.2009(Monday). I am glad that I passed all papers in part 1. I get the highest marks in Accountant in Business(F1), which emphasize more on management,economic and internal control of an organisation. Apart from that, I get an average score for Management Accounting(F2). This paper will served as a base for F9. Moreover, I get
a border line marks for Financial Accounting(F3). Anyway, I am lucky to pass F3 and I would do more revisions on F3 especially topics on partnership,direct and indirect cash flow and sales taxes.
