I have listened to all the lectures for the F5 exam and now revising for this topic using BPP text book also but the text book goes into much more detail and is starting to confuse me (a lot). Is it possible to pass this exam on all the information that is provided by open tuition as long as I do practice questions??
Yes. Our lectures contain enough to be able to pass the exam well.
If you have been through the lectures (and feel that you understand them) then you should spend your time practicing as many questions as possible from your Revision Kit.
I would only bother looking at the Study Text if you come across something in a question that you do not understand or have forgotten (but even then you are better asking in this forum than spending time on the Study Text).
