Well, first of all, these answers are just for in-class participation and the prof will only ask the basic question within the article so it won't be hard. And we need to write a lot of essays, thus I need to read a lot of reading to see if they can be used for my references. But I can't get all the arguments or cases wi the abstract, then I will use Briefy to get the full summary. That's why I said it is productive. And also for videos as well, Briefy is designed specially for YouTube videos, and you can watch the summary, jump to the clip you want right on YouTube with its Chrome/Safari extension. I think you can have a try first, it offers a free plan with 30 credits.
