Any guidance / suggestions will be much appreciated.
In my opinion I would say, sit either for F5 or F6 in Dec 19 if you want to pass well as you have the full time work to deal with. I am in a similar sort of situation as you and sharing only my thought with you. Thanks.
I agree with what Sultan has said. Both of these papers require a lot of question practice and to really understand the syllabus carefully. It is better to take them one at a time, practice well, and pass them on first attempt.
Just a humble opinion :)
In my opinion since you have a full time Job, I will advise you concentrate on one at a time. that is what I am currently doing. It is not about how good but how well. :)
It might quite opposite to what people tell but it totally depends on your study plan and dedication. I've done F7,F8 and F9 togehter with full-time work. But my company had given me 1.5 weeks of study holiday and could leave early on few days.
So if your company can't do this , still do your math and not sure about daily chores but a study of about 3 hours a day from now can definitely help you pass atleast 2 subjects WITHOUT cramming at the end.
Hope this answer helps.
