Just found something out. If you go to shadowfall.killzone.com I believe the address is, it will give your MP stats. On my phone I hadn't really noticed, but on my tablet I saw a Challenges tab, on second look it's there on the phone as well. If you go under Profile the first thing that comes up is the Stats Overview, click on Challenges and you can see what you need to work on in the MP. Really cool, been working on them but you can only check them at the main screen and not in a match. Now that I know this, can work on them more easily in game.
