I'm a fresh beginner, been golfing for 2 months now. Since I sort of cannot afford a teacher, I'm focusing too much on online videos and forums especially this one here (which is great btw, kudos!).
I'm basically the sort of chap who likes to build things on solid foundations, so in golf, it's almost always the driving range, 5 buckets per practice. One for the driver, and 4 for the different irons. And I basically practice once to twice per week.
I also do around 1 hour of putting practice.
At the club where I go to, they have a 3*PAR3 practice course. I have tested it twice lately, I'm hitting the putting green between 2 and 3 shots, but still my biggest problem is still the putting.
But bottom line, the point is that working on the score in the beginning is not helpful at all IMO, because it's random, one swing you might do ok, the other could be devastating.
