My grade in first semester (continue)

I got a "A" from Law of Person. I got a "A-" from Thai Legal History. I got a "B" from constitutional Law. And I got a "C" from Introduction to Legal Principle(almost fall). Many students fail Introduction to Legal Principle. I think it is one of the worst subject in this semester. My friend calculated my grade for me. It came out about 3.38. It is good for my first semester and my mother did not complain about it. This semester, I think the subject that will bring my grade down would be Introduction to Economic. Because I cannot understand what is the teacher teaching? And many students agree with me.
