With the development of technology, life including our study replies on it more and more.
Taking notes is the very traditional method in our study, however, more and more students take pictures instead of taking notes. In my opinion, taking notes is better as people's brain is using in the process and we can remember deeply during the hand writing. Also, the purpose for the study currently is to pass the exam, taking notes is a daily practice.
Apprantly, taking pictures saves the time especially in our extensive study. But we have to face the real exam by hand writing as a student. So, let's take notes for the time being.
