求大侠们帮我改下语法
To be an engineer,you need to be precise,knowledgeable,and sometimes creative.As a student,I have confidence on my preciseness and attentiveness because carelessness is rarely the reason that I lose mark during exams.I don’t doubt my ability on management and leadership as well,but since I spend most time with more intelligent students; I tend play a supportive role rather than being a leader myself in most cases.However,I can judge others ideas and sometimes make up better ideas by combining the strengths of other’s thoughts.You can use methodical to describe me,maybe a little conservative as well.Unlike most energetic high school students,I like to have more privacy instead of filling up my schedules with various social activities.As a result,I can concentrate better on school work than most students since I have less activities to spend effort on.For creativity,I won’t spend time on attempting to create something unless a specific purpose has been clarified.However,if I do try to creative,I will put my best ability in it.Anyway,I have confidence on being an engineer in the field which I am interest in.

In my opinion,to be an engineer needs to be precise,knowledgeable,and sometimes creative.As a high school student,I have confidence on my preciseness and attentiveness,because carelessness is rarely the reason that I lose mark during exams.And I also believe in my ability on management and leadership as well,as I can judge and make up better ideas by combining others’ thoughts.While since I've spent most of my time with the intelligent students,I know that playing a supportive role is actually more important than being a leader by myself in most cases.You can use methodical to describe me,maybe a little conservative as well.Unlike most energetic high school students,I like to have more private space instead of filling up my schedules with various social activities.That’s why I can concentrate on my school work better than others as I have less activities to share effort on.For creativity,I won’t attempt to create something unrestrained before a specific purpose has been given.However,I’ll also put my best in it once I try to be creative.In a word,I have confidence on being an engineer in the field which I am interest in.
