Feeling bored now

我也写下中文表达，这样不仅能让你们更好的帮我修改，还能帮你们学习中文 [Thank you very much!]
。
我总是不得不来教室上那些我完全不感兴趣的课，比如高速公路机电系统新术及其用
在中国，大学课堂总是需要点名，你的国家是这样么？你们进大学选专业是根据分数线决定还是只要通过申请就可以选择自己喜欢的专业。) 

I always have to be in the classroom to learn these boring lessons, for example, new technology elctro-mechanical systems in high speed transportation. New technology and application of highway electrical and mechanic system. We have to sign our name almost every class in for classes in Chinese univesities.China. How about Is it the same in your country? Are you choosing the major by grades.(i mean every major in every collage have a grade line,you can only choose if your grades are higher than that.) or by interest after being admitted? Your choice of major is limited by your grades and only after an interview.

This is translation by meaning, not by parallel translation.  This is okay for this sort of essays when the intent is more important than nitty-gritty details. 

This is a bad system.  Having good grades should not be the main deciding factor. Aptitutde should be the criteria.  Edison never enrolled in any invention classes.  Here in the US, you just have to pass the exam to see if you have the basic knowledge to understand what you are studying.  People should have the choice in what they love to study.  If this is the case, the Chinese Imperial Exams would make the dynasty last forever because only the best are chosen to become civil servants.  The US will always lead in technology and invention because of the absence of these barriers.
