Okay, I'll be a bit more helpful:
1. Read over other posts here; this site is a great resource.
2. Consider taking a prep course and/or hiring a tutor.
3. Purchase the three GMAT Official Guides and a prep guide from one of the GMAT prep companies.
4. Practice the questions in the Official Guides, applying techniques you learn in your prep course/prep guide.
5. Return to this site with specific questions; people are always happy to help.
Good luck!
