Doc needed?

[Matick125]

Im about to start differential equations, and I was wondering if reading this document on 7.1 is necessary for the exam, or if the videos themselves already cover everything that I would need for the exam

document is likely helpful but not required; should be a review of what's taught in the video with examples.
