well what i do to get alot of points i got over 200+ pera game in CTF when its badlands i believe and u stay at ur flag and theres a rocket launcher right there on the roof above that respawns every 45 seconds, just stay on the roofs and shoot the enemy warhawks down ( takes 2 shots if rockets hit them ) and the enemy team always rushed for your flag in Jeeps, Tanks, APC's or on foot. and course you have a rocket launcher so 2 shots to a jeep, 2 or 3 for a tank and apc its 4 shots. and then 1 shot for runners, and u get extra points for killing the enemy flag carriers.
so i did that and last night the most points i made in 1 32 man full game was 316 i believe. BUT! ( make sure your on the blue or red team whichever is getting attacked the most ) cause then you kill so many people who are trying to take the flag, and also once and a while go capture the flag for around 5 points for taking and 10 points for capturing ( this was what it was like for the server i was on )
heres what i do, i either play CTF in the badlands fort area like afro said and i also play collection. In collection just focus on the cores and bases get alot of cores = 80+ points. Get all the bases plus enemy bases = 20+ points
