Congraulations Marshy on your achievement :-) really appreciated

Since you have passed exams upto Management levels by home study, I think you have that 'extra ability' to grasp concepts better and thus you may pass your exams with whatever the learning course you may select (Just what I think about you). With regard to pass-rates, I don't think BPP or any others would have such a comparison of Online study pass-rates v/s. home study & classroom pass-rates. BPP itself offers all such study options and they will never compare pass-rates between their own tuition modes.

If you are really considering an online option, I think better you try with Insaf live online as it's one of the best online tuition services considering the tuition quality. BPP online classroom is just pre-recorded lectures with study material and off-line tuition support. I've learnt with Insaf live online and their courses are offered on a 1-2-1 basis with 'live' personal tutor teaching online. It has added flexibility of arranging sessions at our time of convenience and the same tutor coaching us throughout the programme. The tuition is also excellent and I compared BPP prices to insaf prices - that we can get 35 hours of 1-2-1 personal tuition + study material from insaf live online for the price of BPP's recorded lectures - INSAf live online is really worth the money! 

Wishes for your Strats :-)
