C01 book + exam practoce book (KAPLAN) + Opentuition notes and lectures

Hi there,

I still have my c01 coursebook and the revision kit (practice Qs and mock exams) from kaplan

Will it suffice to use these two books as well as the notes from Opentuition and lectures to pass the exam or should i purchase the BA2 book ?

I have already started using the c01 book (finished 4 chapters) and then realised that there has been changes since i last intended on starting the course.
