This is not a scam. The short answer for science preparation is the most effective answering skill obtained by sorting out and summarizing the learning experience and methods of the top candidates in the college entrance examination over the years. Students can improve themselves by learning skills. The "Short Answer for Science Preparation" project helps students in Grade Three, Grade Two and Grade Three to provide zero-based learning and live experience. On the basis of inherent learning, they use scientific methods to solve difficult and error-prone problems. This project can help students improve their college entrance examination scores by 80~ 100, and the art students in senior three can improve their scores by more than 200.
