High school students should be required to study many different subjects at the same time or they should study only three or four subjects at a time.

Lifetime[ wrong word ] during high school is of great significance for students when [since during which  ] they develop [ a good ] the habit of learning [ habit ] and foster positive values. Some[unclear pronoun  ] are convinced that students should take various subjects at the same time[ unclear sentence ] . As far as I am concerned, I’m against that idea. [ With respect to this attitude, I argue that students ] Students shouldn’t[ avoid using NOT ] take too[ should refrain from taking/matriculating in ] many lessons concurrently.

To start with,[Admittedly,  ] learning 3[ three ] or 4[four  ] lessons[subjects  ] at a time helps promote study efficiency. (For one thing, It is obvious that a large sum of time is necessary in order to achieve a good grade.)[unclear  ] With fewer classes[ courses ] to attend, students are able to [can  ] devote more time to [ the learning of ] one single subject. As a result, they can do better in[, thereby achieving better/optimal  ] academic performance to earn an edge over others when hunting for jobs. For another, [ since ] some elective courses [ are less ] may not be as important as [ than ] the major [ ones, students ] . Students can easily [often  ] fall asleep or find their minds wandering [become absent-minded  ] in class because they have lost interest in it[unclear pronoun  ] . Such time that could [ otherwise ] have been [ be ] spent on the major is wasted, leading to a low study efficiency.

Additionally, without[liberated from  ] the heavy burden of various classes, students can have spare time to participate in extracurricular activities which[that could  ] improve numerous skills. First, taking part in physical activities is essential for students. For instance, joining a football team fosters one’s team spirit and perseverance. Students will spare no efforts to win and never give up. (During exercise, students both possess a healthy body and relax,)[unclear  ] which lay a solid foundation for their busy studies. What’s more, hanging out with friends or joining parties from time to time will train students’ social [socializing  ] skills. No man is an isolated island[use your own words  ] and it’s essential for students to (get hold of )[wrong phrase  ] the ability to communicate with others and maintain a good relationship [ , ] which will be an advantage in [ benefit their ] future work.

[In light of my arguments noted above, I propose that  ] It is true that students should have a general view of different subjects before choosing a major. However, it is hard to ignore the fact that too [ learning ] many subjects to learn at a time will wear away the interest of all the subjects.
