Here are the chords you will need to know in order to play these chord progressions:
A, A Minor, C, D, D Minor, E, E Minor, G
I have included videos below which demonstrate how to play these chords:
The A & E Chords:
The D Chord:
The A Minor, E Minor, D Minor, C, G
Watch the videos above and practice those chords first. Then start practicing the chord progressions below.
For the 
chord progressions, strum each chord 4 times with a down up down up strumming pattern. Or you can take a look at a post I put together on strumming patterns to make these chord progressions a bit more challenging. Go very slow in the beginning so that you will be able to change chords smoothly and accurately.
You can test and see if you are playing each chord accurately by playing one string at a time on the chord. If you hear any buzzing , or if any of the notes sound muted, you are either not pressing down hard enough, or one of your fingers or your hand is touching another string.
Here are the Chord Progressions:
G -- C -- D -- G
G -- Am -- D -- G
D -- G -- A -- D
D -- C -- G -- D
D -- E Minor -- A -- D
C -- Dm -- G -- C
E -- D -- A -- E
I know this all seems very difficult in the beginning, and it may seem that way for some time. The most important thing to remember is to never give up.
Eventually your hands will become stronger, your chords will sound cleaner and your chord changes will become faster.
Enjoy and Happy Guitar Playing!

HOW DO FIX A STRING

Thank you for your wonderful comments and your questions. I am happy you are enjoying the website.
KK: You asked, How to fix a string?
The only option you have is to replace the string.
Replacing a string takes a bit of practice, but it’s not as difficult as it may seem.
I put together a post not too long ago that includes links and videos which demonstrate how to change your guitar strings.
Here is the link:

I hope this helps!

well going back to the broken string, there is a way to mend a broken string. however it should be replaced asap because that is the best way to handle a broken string. if need be and your string snaps suddenly,depending on where the break is at it may be able to be fixed by simply twisting the two ends together until tightly wound and proceed to re-stringing.
