I failed AB with 49%

Sorry to hear about your AB fail. In AB you might know the theories but not be able to apply it so well. That's why question practice is very important using a revision kit from BPP (20% discount if ordered through this site) or from Kaplan. If you haven't had a lot of question practice then you need to remedy that before you resit. If you already have used a revision kit, concentrate in going through that for your next attempt. Depending on the time you have each day, 7 days would be possible. There is no reason to think you cannot do ACCA. I always think AB is a bit odd. It is not of huge direct importance later in the qualification. F3 is much more important - and you passed that.

same I failed Ab with 49,in my first attempt now,I am confused how is its possible after so much time I put on my studies, what I discover is that AB has trick questions and needs so much understanding I hope next time will make it with high marks. all the best to all acca students we can do it.
