How to pass RES exam in a single sitting

I have been wanting to write this posting since I passed my exams in May 2016. My husband did the exam at the same time but he only passed Paper 1 and re-tried Paper 2 twice. My ex-colleague’s husband tried 3 times and didn’t pass. My step-bro also tried in June this year and he didn’t pass. I start to wonder if the passing rate is rather low for RES. 

I do not have a special secret to it. It takes much effort to digest the thick set of materials provided by the school. By the way, I went to Pioneer Training & Consultancy (which I attended an 8-weeks crash course). 1 month before the exam, I studied every chapter and wrote my own notes. I will recommend to start earlier as it was tough to squeeze the effort to just 1 month. The school also provided an online MCQ and open-ended practice questions which I diligently did all the test questions and revised those mistakes. Initially I panicked because I failed almost all the test papers in the range of 10-20% passing mark for each topic. The open-ended questions were the toughest as I could not make an intelligent guess. There are many new legal / industry words which one may need to understand, and also memorize (spelling). Do not underestimate even simple key words as they may appear in the section of fill-in-the-blanks. I personally believed that the fill-in-the-blank section is what determines whether you pass or fail. If I were you, I will list down all the possible key words and make sure to memorize them.
