Note-taking without a real note

It is horrible when you are living at 21st centuries. However, papers are dominated in your life. In fact, more papers are adapted in electronic form instead of a bunk of sheets.

I understand that some may say using paper is better than staring on the screen. However, I would say, there are many benefits for you to use digital-inking.
Paperless Learning

As a student, it is quite common to see my classmates print the slides out. In a big contrast, the companion for me are the MacBook plus a drawing board. Beyond ticking the attendance, no pens would I use during the class.
Then, a drawing board, as I mentioned, you probably guessed how I jot notes in the class. It is the almost identical to others, I do need to handwrite every keypoints from the speaker. However, my approaches is, using an app called Notability. I note every essentials into the app, digitally.
Tools mentioned: Wacom Bamboo Pad (official introduction) + MacBook Air + Notability (official website)

The way to mark unfinished lesson

Sometimes, as experienced, the lecturer cannot finish the entire class. Therefore, I mark the Part and Date into the slide stopped.
It can keep tracks of my lesson too.
Not yet! OneNote!

Indisputably, it is not sufficient when you merely to take notes during the course. Instead, second processing is important for everybody.
For me, I use OneNote to organise the lesson. Copy and Pasting is, of course, the basic for me to do. After that, the meaningful part, making things more memorisable.
