I shared your view that self study is quite important & over reliance on lecturer alone is very risky indeed.
Last time in my cat i take all papers at only 1 centre, as aresult i learn the hard way that some of lecturers are not competent enough.
This situation forced me to study even better as a result i scored eighty above (cat difficult is still ok for tax only = 90% similar)

However i notice a flaw in your comment which can be rectified further.
Evidently you take all your papers at single college (perhaps for bulk discounts, convenience or follow friends around.....etc)
In acca level 2 (f4 to f9) its quite difficult to self study as there is many changes in syllabus than you expected.

I can highlight some aspect you will probably face during self study :
1) Confusion = there are some very weird topics around which requires explanation

2) Lack of focus = Not all areas will be tested & you may study something which will never even be tested.

3) Changes in content = Areas like audit & reporting face changes every 2 sittings at the very least.

4) Lack of experience = This is the major point highlighted by many UK forumers (if you are interested), you may not know how to detect common mistakes made by student.
- In tax student always thought they will socred but always get lower mark than expected.
- In reporting many student think they will scored one evry a/c blance but its just an illusion
- In audit student always thought knowlege may carried them through but examiner is very peculiar about wording which student always get wrong

5) Wrong technic = You may know the answer but do you know how to structure ?
In audit examiner are very peculiar about the wording when you use audit procedures for substantive procedure ot test of control.

Of course you can self study but you need great discipline to do so. Normaly students aged <23 lack the ability to do so.
You have mentione dthe reason why you go for self study yourself = bad lecturer.
So the solution to your problem is to find "an even better" lecturer.
Because you paid for it you have every single right to ask & choose the best lecturer to suit your study needs. It doesn't mean the best lecturer in the market will be most suitable for you. Choose wisely & find where is your weakness is.

Beacuse i was weak in theory part in reporting i look for the best lecturer for reporting theory.
Because i need good technic for audit not only the knowledge & experience i find a suitable one.
Because i need a good lecturer who can explain the reasoning of models & framework of finance again i go for the appropriate one.

law is the most suitbale paper for self study but its the most boring paper in all acca.
If you enjoy the learning process you can understand it better & there is no better lecturer in doing that (that i know of) than Viknes in KSA & KB.

i plan to take f6 for the june 2009. anyone noe who is the best lecturer for this paper?
