How can I become faster in breaststroke?

Im fast in breaststroke already but I would like to be faster. My current time is 38.90 sec. and I swim in the 13-14 year old girls group (50 yards only). im 14 and have 2 weeks to prepare for our city meet. Any tips on improving my time?|||When you practice, concentrate on the parts of your stroke that you think you need to improve on (ex. whip kick, arms). This will help you go faster with less effort than simply practicing breaststroke.|||Practice as much as you can.
