80% pass and How I studied

I have passed F4 CBE (English) with 80% pass. I think it was lucky which contributed to my score though. I studied by myself and spent a month to study. I know it is a long time but this was my first exam so I put a lot of effort in, also I wanted to see if I could study on my own without going to centre.
I studied all chapters from BPP text books and did the kit book three times.
The first time was after reading each chapter.
The second time was when I finished the whole text book, I read the note from opentuition and did the kit book again.
I then read the text book second time. Now I understood more because I could connect the relevant knowledge in different chapters together. I did not really understand what the book tried to tell me at the first read. I did the kid book again 🙂
When I do a question, I choose an answer for it but at the same time, I explain to my self why other options are not right. Therefore, I remember longer and could answer similar questions. The questions in my session were similar to what I solved in the kit book however in different aspects.
My advice is to try read all examples and cases in the text book because the questions use these backgrounds.
