Students have to write papers and give oral presentations. I think oral presentations are better because they are easier and take less time to prepare. Another reason is oral presentations are interesting for other students who are listening. Finally, many jobs require oral presentations. Therefore, students can learn an important skill and develop confidence in speaking to a group.
I think writing paper is better for students. Firstly we need to develop strong writing skills. We go to school mainly to learn reading and writing, so we need a lot of practice. Exam requires a lot of writing, so writing papers is good preparation. Also, I think writing is a better way to show that I understand. When I write a paper, I can think deeply because I have more time to explain my ideas.
