Against Me - Even At Our Worst Were Still Better Than Most Chords & Tabs

I think this tab is fairly accurate but if anyone has any suggestions please feel free 
comment. I used F, A, Bb and C ALL in power-chord form in regular tuning:

  F  A  Bb C
--1--5--6--8--|
--1--5--6--8--|
--2--6--7--9--|
--3--7--8--10-|
--3--7--8--10-|
--1--5--6--8--|
[ Tab from: https://www.guitartabs.cc/tabs/a/against_me/even_at_our_worst_were_still_better_than_most_crd.html ]
These chords are used throughout the song for the intro, verses and chorus'.

Intro:
F

Verse 1:
F-A-Bb-C x2 then play with distortion

Chorus:
F-A-F-Bb
F-A-F-Bb


I'm still working on the solo and outro part but if you guys want to finish it up, it's 
not too hard. Thanks!
