Sorry but you can't just walk onto a golf course and practise for free, what planet are you on? Don't you feel awful doing this? Why not at least ask first before trespassing, I would ask you to leave if I saw you doing this.
The fastest way to lower your scores is to hit the ball on to the fairway, or green from the tee, anyone can two putt, but can you hole the 3 footer on the final whilst hundreds are watching?
The par 3 tip is good, but you need the equipment. 7iron, putter, wedge, and 5 wood are all you need to learn golf, but take a course of lessons and do not keep changing the pro, afterall the beginner knows nothing and the Pro knows everything, so please trust him/her, AND EXPECT 3 MONTHS OF STRUGGLING BEFORE YOU MAKE PROGRESS.
