The four courses of Hyman Education are an educational course mainly aimed at primary school students. As far as I know, the four courses of Hyman Education are a comprehensive course, including Chinese, mathematics, English and science. The goal of this course is to help students systematically learn and master the knowledge and skills of these subjects.

The teaching methods and contents of the four subjects of Hyman Education are designed and adjusted according to the characteristics and needs of learners. Through a variety of teaching methods and activities, such as classroom explanation, practical operation, group discussion, etc. To help students better understand and apply what they have learned. At the same time, the course also focuses on cultivating students' learning ability and comprehensive quality, and improving students' learning interest and motivation.

But the specific teaching content and effect may be different for different educational institutions, teachers and students. I can't give a definite answer whether the four courses in specific educational institutions are true and effective. I suggest that you make an evaluation and decision by consulting relevant materials, understanding the educational philosophy and teaching methods of this institution, and consulting other students or parents.
