So since I have played CS:GO since release,
All I have to say is, Don't believe in what the community says.
If you're going to play csgo, buy prime. Seriously, buy prime.

Matchmaking or MM as it's called. Remember that rank is just not that important.
Your rank is there to make sure you have a fair game. It will go up slowly with time the more you improve. Don't try to improve too much at once and tire yourself out.

Have a fun one.
Also if you see a cheater just report him and move on.
Do not make your trust factor go down deep by being a bad guy.
