I have an exam for differential Equations in 3 days and do not understand anything!?

What should I do? The book I am using using is called "A First Course in Differential Equations With Modeling Applications" in 9th edition by Zill D. I fell behind in this course due to my bad habit of procrastinating (which I will not do again) and didn't attend class. What can I do to actually understand this in depth and dumb it down so I can understand wtf is actually going on? I was thinking "Differential Equations for dummies", but I do not know if the book gives challenging problems and if it will help me do well on an exam. What about online youtube MIT lectures? If anyone has any good free resources out there, please let me know ASAP! Thanks!

Read the text again and borrow someone's notes. Otherwise you'll just have to make the best of it. You can't learn a course in 3 days. There is no magic bullet for you.

It's not the whole course just like 5 sections from the book. It's a midterm, not a final and it is not cumulative.

My argument still holds. What topics are you missing?

I agree with the not understanding anything part. That book sucks.

I am currently using that same book.

Did your teacher give notes. That's how I am getting by. Otherwise There is no way you will master all the info in 3 days.

I know all those topics well but there is no way to learn that in 3 days. I been studying like crazy to know what I know on those sections you mentioned.
