Dear BSUGrad,
You're currently using a Starter Putter, which is low on Precision and Forgiveness. Precision is how accurate the ball will travel to where you were aimed. Forgiveness is how much variance the ball will have when you don't hit the "ding."
It is recommended that you upgrade your putter to any of the higher putters before complaining about the games physics. I'm not saying you're a lying scumbag who sucks, but I am saying there are many ways you can improve your game, and upgrading your putter is one of them.
I personally recommend the TaylorMade Rossa Daytona Putter for 750 ($7.50) credits. If you're not looking to spend that much money, feel free to rent any of the other putters to get a taste for them all in the Putters Section of the Pro Shop.
Practice will really help too, putting ability definitely won't come to you overnight... it's been 9 months for me and I still don't fully understand it!
