What kit do yopu guys normally go for? I pretty much stick with assault and have unlocked a fair few weapons im only rank 6 mind you

The problem i am having is i always seem to get a low score even if i say kill 10 and die 10 times someone who has killed 4 people and died 10 times will have way more point than me. I always throw ammo out for people am i missing something to gain extra points or shall i take it that im just rubbish lol
Spot everything! Enemy infantry, tanks, apc's and choppers. Always join a squad, you get extra points for helping squad members. Spot flags and then cap or defend to get extra points. If you jump in a Black Hawk chopper as an engineer and you don't get a minigun seat you can still earn repair points by pointing your drill gun at the roof to repair it.
SPOT EVERYTHING!
Medic is probably the easiest way to earn points without having to be any good at shooting. Throw health packs down at every opportunity, they don't disappear until they've been used up, so you can heal people from all over the map. Revive team mates, but don't run over open ground to revive someone. Only do it if you aren't going to die doing it.
SPOT EVERYTHING!
If you play as recon, then use the scope to get a closer look at the battlefield and SPOT everything. Throw motion senor mines to get even more spot assists and rain down mortar fire on groups of enemy soldiers or tanks camped at a distance.
SPOT EVERYTHING!
As an engineer get in a tank as the gunner, spot enemies as you see them and get out an repair your tank as soon as it starts to take damage. Unless it's damage from mortar fire then hopefully the driver will move and repair then. Tracer enemy vehicles, you get points for a hit and even if you don't destroy the vehicle you get tracer assists points as well.
SPOT EVERYTHING!
As assault, throw down ammo packs at every opportunity. Like health packs they stay on the battlefield until they are used up. You can also take C4 with some weapons to take out enemy vehicles or plant at objectives to set off when they are under attack. You can also unlock tracer dart pistol and use in the same way an engineer does. When shooting enemies, tap the fire button to maintain accuracy and if you run out of ammo switch to pistol, it's quicker than reloading. They are very powerful and can down a full health enemy in 3 shots.
SPOT EVERYTHING! SPOT EVERYTHING! SPOT EVERYTHING!
