HAM pre-exam practice is specifically designed to reinforce exam knowledge. It draws inspiration from the well-known "Nine Zones" training software model, utilizing memory curves and repeatedly practicing correct and incorrect questions until mastery is achieved. Therefore, a complete review of the Nine Zones training is highly effective in solidifying exam knowledge. I recommend reviewing it at least twice; you will find that after seeing some answers or questions, you can easily identify the correct answer.
Furthermore, the mini-program also provides specialized training, specifically targeting exam areas where CRAC produces official questions. It can precisely identify different question types, such as those using Q-simple language (Q简语), allowing users to focus on practicing only that specific section if they are unfamiliar with Q-simple language.
