(adsbygoogle = window.adsbygoogle || []).push({}); So this is just a quick guide on how I found was the fastest way to rank up.
(this guide is intermediate/advanced players)

So for the low levels (I love this part) make a class with a Smg (I use Ump) Marathon, Lightweight, Ninja (commando if you want to be like that). So because you are a low level and each kill is 500 points, Headshot 1000 points and plant 1000 points you can level very fast... Why i had you make the rush class is because you are going to try and take the bomb rush to a plant site (killing as many people on the way) and plant bomb fast! At a low level you don't care about winning the rounds because match bonus points aren't very high. You just want to Kill, Plant, Gaurd... Kill, plant, gaurd... as for when your on defense just use what ever class you think can get you the most kills.

At higher levels 35-40+ you will notice the match bonus point start to because more significant.. Now you want to become the Team Player, for me this is snipping i cover my team and just try to make sure we win at all costs. For you just use a class that you think will make your team win, don't just rush and plant because that causes your team to lose a lot.


Over view

Low level:
*Rush, Kill, Plant!
*You are a lone wolf play for your self just get kills and points

Higher Level
*Play for your team
*Make sure your team wins and you get your bonus points.

So that was my quick guide to level... I put this together in just a few minutes and Its just what works well for me, i have gone from 1-70 in a day (after i got my wisdom teeth pulled). I hope this can help you guys and please don't spawn tube, Oma tube, gernade spam, or do anything else like that it ruins the game i know i said do anything to win but don't do that.

Good Luck ranking up! (sorry if i misspelled a lot of things I'm quite high right now why else would i write a rank up guide?)

Oh and why i said for intermediate/advance player is because if you are bad you might have trouble picking up a lot of kills in SnD the people tend to be better, you might want to play ground war or something and try to complete challenges.

thanks to ethon123 for this
