I need help with Astronomy!!?

There are more appropriate books for your age and educational level. Robert Dixon authored Dynamic Astronomy, which has gone through at least seven editions. While a bit out of date (nothing on exoplanets for example) I think it would be better for you. An even better idea is to go to the website of Sky & Telescope magazine (skyandtelescope.com) and look through their book reviews for an up to date book on your level. This also is an excellent source of current information.
