Yess, LeechBlock is your best friend.
I prefer taking notes on a computer. I type much faster than I write, I can capture more information, and it’s easier for me to move that information around later when I need to organize it. I also don’t have to concentrate as much on the process of typing as I do on writing, which means more of my attention is on the speaker.
If you have a computer with a touch screen you can easily use a stylus or your finger to draw diagrams and charts. This wasn’t an option when I was in college but it is now, especially if you have a computer that folds around 360 degrees.
I use Microsoft OneNote to do most of my note-taking. In fact - and this is going to make me feel old, lol - my college class got Microsoft OneNote given to us for free because it had just come out the year before I started college, and they wanted more college students to try it out and advertise it to their friends. So I started using it about 12 years ago, and have just used it ever since then. You can draw directly on a OneNote page right around any of your words, and you can also insert drawing tools. Evernote is a decent option as well.
