If you're talking specifically about top rope problems, a great way to up your game is to gain a reputation as a really good belay partner. It sounds weird, but spending time on belay teaches a whole lot about tempo. In my experience (I'm a mediocre climber), tempo is the biggest thing that separates novice climbers from mediocre climbers.

Otherwise, climbers tend to be extraordinarily friendly people. If you're stuck on a problem, feel free to ask someone for beta (advice on a problem). There is some etiquette involved (ie - don't ask someone who is on belay), but as long as you're humble, you will find climbers who will help you solve problems you once thought were insurmountable.
