I'd say two things to you:
1. Evolution is a fact.
2. If you are serious about learning about problems with evolutionary theory, you first need to learn about evolutionary theory. Yes, I know you've been learning about it in school. Trouble is, the level of evolutionary theory you'll learn in school is way short of what you'll need.
By analogy, I imagine sometime around now they're teaching you that electrons orbit the nucleus of atoms, probably shown you some diagrams that look a bit like the solar system? Pack out the shells in a 2, 8, 8 pattern? They don't actually do that. If you go to A-level and they'll tell you a different story, same again at degree level. What you're learning now is an approximation to the theory, a simplified model to give you the basic ideas.
So, I suggest you read
The Origin of Species. It's kind of out of date, and the nineteenth century language and style can be hard to follow at times. But it is a tour de force, and unlike most modern books doesn't assume you have any idea what evolution is about. I rather like Dawkins;
The Selfish Gene and
Climbing Mount Improbable are worthy books, aimed at the lay reader. However Dawkins rather rabid atheism might stick in your craw.
Others here can probably suggest some other good books on evolution, and probably some more technical references?
