Honestly focus on ball impact drills. Just like putting the most important part of any golf swing is between your feet or a 3 foot zone. If you can putt, chip, pitch you just need to build consistency on the range with irons. Build a preshot routine that forces you to swing through an impact spot and keep the club on target. To many new golfers just swing. Which is fine but if you want to get better watch some good golfers. They all have a routine of picking a spot in front of the ball and aligning themselves to the target.

Good luck out there! Its a challenging sport but extremely rewarding as you continue to learn and hit great shots.
