The only way your EVER going to learn to be a decent, forget about great, pilot is to actually fight and die. Score shouldn't be a thought in your mind right now.
You can BnZ or hit and run, but even then, while your booming, someone else is already climbing to get co-alt with you on your zoom. Someone with a faster, or better turning plane then yours. What do you do now, run for your life and hope to make it home, or shoot them down?
If i were you, at this point in the game, i would pick 1 plane, turn stall limiter off, turn on your flight recorder, and fly it to every furball. Fly there between 2k-6k with 50% fuel and no drop tank, and engage anyone and everyone. Base defense is another way. Your going to die ALOT, but your SA, gunnery, acm, and communication skills will double. Just get in there and fight till you die, or there are no enemies left to kill.
Review your films, and make mental notes of what worked and what didn't from sortie to sortie.
Try and stick to 1 plane for now.
