This time we gave you a great introduction on how, to begin with, sketchnoting by James Thomas.
First of all, you will learn how to make plain old text notes. What to note and what to dismiss. Sketchnoting adds additional visualization that should amplify what is important, which could help you memorize punchlines.
I tried sketchnoting, but during the conferences, they slow me down. When I read another tester sketchnoting from me, it is tough to grasp the talk’s essence. I think that sketchnoting is as plain old text noting, only useful to the author. For me, the Cornell method is what works. It helps me summarize the conference talk to write a blog post later on (one-week time-window max!).
But you should definitely try it. If sketchnoting had not failed me, I would have never found about the Cornell method.
