Even so, I suggest you read more original questions, because if you read more, you will basically understand the style of the questions, which is conducive to your targeted review. I made two exercise books (a basic knowledge and a law) in the exam that year. That is a set of exercise books for futures examination published by Sung Hoon, which is not more than ten yuan expensive.

What I found online is not reliable. There are some courseware on Douding, which is more useful. I did two exercises and watched the courseware. There is basically no problem. At that time, my basic knowledge was 89 and my law was 85.
