This is only my opinion and advice,
play 1 course at a time and take notes of everything, it will help you learn where to aim and where you can miss and give you the best chance to still score. then do the other courses.
Practice putting !!!! its the hardest part of the game but will lower scoring avg the better you get at it !
Learn all the shots ie.. full,punch,pitch and chip and where they work best at !
there is alot of useful tips in FAQ's
then practice and play alot ! you will get to where you need to be when you are ready, dont rush it the competition is fierce on here !!
Good Luck !!!
