During this time, my main focus is exams and homework.
The coursework and interaction here are very different from those in China; it is still a bit novel and somewhat difficult to adapt. A large part of the assignment and discussion of the assignments was made on the network system. The teacher's office time can play a large role for students to receive help. You can discuss many academic and professional development issues with the teacher.
I also had to learn to cook some food to adapt to the rhythm here. Coming to Berkeley is always in the process of learning and progressing.
