Mathematics: Mathematics needs abstract thinking and logical reasoning ability, which may be difficult for some students. Formula derivation, geometric proof and complex calculation are the difficulties in mathematics learning.
Physics: Physics involves the explanation and understanding of natural phenomena and requires students to have a strong mathematical foundation and reasoning ability. Understanding the laws of physics and solving problems with formulas require higher abstract thinking.
Chemistry: Chemistry involves the composition, properties and changes of substances, and it needs to master complex chemical concepts and reaction equations. Chemical experiments also require rigorous thinking and experimental skills.
English: For non-native English speakers, English vocabulary, grammar rules and listening comprehension may be challenges. At the same time, reading comprehension and writing also need long-term accumulation and practice.
It should be noted that this is only a general statement and does not apply to all students. Each subject has its own characteristics and difficulties, and different students have different academic advantages. It is important to face difficult subjects positively, arrange study time reasonably, seek the help of teachers and classmates, and study and practice persistently according to your own situation.
Junior high school is a stage of compulsory education in China, which usually includes grade one, grade two and grade three. The academic system is three years. The main subjects in junior high school are Chinese, mathematics, English, physics, chemistry, biology, politics, history and geography. In addition to subject knowledge, there are elective courses such as physical education, music, fine arts and information technology.
The educational goal of junior high school is to cultivate students' basic knowledge and skills, cultivate students' thinking ability, creativity and practical ability, and lay a solid foundation for entering senior high school and future study. According to the subject characteristics and students' cognitive ability, junior high school has set the corresponding course content and teaching objectives. Students learn the basic knowledge of different disciplines and gradually expand into deeper fields.
Mid-term and final exams are usually held in junior high school to evaluate students' academic performance and mastery. At the same time, students also need to participate in various competitions or selection exams to improve their ability and competitiveness. Junior high school students are generally organized in classes, with about 30 students in a class. The head teacher is responsible for class management and students' daily education, and helps students solve problems in their study and life.
