Are the P3 notes and video lectures based on the official Kaplan study text? or the BPP study text? Are these study notes along with question practice sufficient to pass the exam? Meaning without studying the Kaplan text book.
Our P3 notes are not based on either Kaplan or BPP: they are our own notes, based on the topics in the CIMA syllabus.
Our notes and lectures, TOGETHER WITH QUESTION PRACTICE (BPP or Kaplan exam kits) should be enough. You should also try the CIMA mock/specimen paper on their website.
If you already have the Kapln text, I suggest you only turn to it if you come across a question where you need more information or explanation.
