批改

If you are student and you want to get a good value, you must understand all what lectuler said, his lesson, diligent to following his lesson, ask with person who smarter than you if you get difficult, add matery from source another like: you get any books in the library.

Do this toward all your lesson in your faculty.

With you do this, you not memorize the lesson again, but you understand consep the lesson so all type questions you will be easy to answer when you are exams.

That's all need a efford so hard, hight motivation, but that's all also just for you to be success in the future.

If you really interest and want become expert with your majoring in the university, so you must hard work to make effort and thats all is no problem about your effort.
