Which chapters are left out during in the anime of Attack on Titan?


I've recently started reading the _Attack On Titan_ manga. I started from
chapter 35 and skipped over 1-34 because that's where the anime left off and I
already watched it.

I just want to know which chapters I should go back and read without having to
reread all of them (because I'm lazy and I know I'll lose interest if I do)




I have read from the beginning. From what I remember, the anime didn't leave
much out if anything at all. It just stopped at a really bad point. The main
difference is that the manga did not progress linearly and employed a lot of
flashbacks.
