Anyone willing to help out a bad player.

I know most threads are aimed at the better players and recruiting better people to get more wins.
I could do with someone who’s able to help out give me some tips on callouts, advise me where I’m going wrong with strafing and grenades, power weapon usage etc.
I’ve been a committed Halo player for quite a while now and it seems I’m not getting better. The game is irritating me as it’s just loss after loss, death after death.
So if anyones willing to help out my gamertag is mark582
