All advise given so far is pretty good. You didn't mention where you bought your bow or who set it up. Did you buy it at an archery proshop? Did you let the pro see you shoot it? If you answer "yes" to both of those questions, then re-read the above posts. If your answer is "no" to either of those questions my best advice would be to go to an archery shop and 1. make sure everything on your bow (and your arrows!) is set up correctly 2. Have them watch you shoot to see if any additional adjustments can be made.

You should be able to get into good shooting form by the time season arrives, if you aren't...don't go hunting. We all owe it to our quarry to be the best that we can. Keep practicing and maybe only a week or two into the season you will be able to hit your mark and still have plenty of time to hunt.
