General ACCAOn average, how many hours did you guys study for F7 and F9?

Yes they are more than enough - but remember it's about the effectivness of study not the 'time amount'. Personally I have never counted hours which I have spent on studying.

1000 hours! How will you manage that? 1000 hours / 120 days = around 8 hours each day!! Do you not work or intend to have a life at all over the next 4 months? You should be realistic about what you are able to do. Make a plan of what you are going to study and be ready about six weeks prior for revision. I wish you luck and admire that you intend to do this much work

F7 - I did weekly classes circa 3 hours x 14 weeks + 3 hours a week + Revision classes, 24 hours + 3 weeks cramming, 60-80 hours, Total = 170 - 190 hours maximum. Got 70%. F9 - I say I did slightly less similar to the above 150-170 hours and got 61%. I just done F8 & P2 in Dec 14 I say I did less than 100 hours F8 & over 220 hours P2. Will get F8 & P2 is knife-edge....so you aren't always rewarded for time you put in.

As another poster said, it all depends on the productivity of your time. 2 hours of quality focussed work is better than 4/5 hours of poor work.
