So, the helpdesk didn't help you with what you needed to know.  Hopefully, these links will help you with whatever you need to learn.  I've weeded out all the idiotic links and left only the very finest information sources on the internet.  Thank me by sending money in small, unmarked bills.

• The Chemistry Coach:  Great tutorials and practice problems by a guy with a really big website! Well worth the time if you can't find what you want on my site!
• Computer Assisted Learning in Chemistry:  The name may be boring, but this site contains some really good tutorial links on a variety of subjects for anyone from beginning to IB/AP students.  Check it out!
• Chem 101 Online Textbook:  Yet more tutorials for students of all abilities
• The High School Hub:  Help for all of your school subjects, not just chemistry!
• The Chem Team:  Tutorials aimed specifically at high school students.
• Chemistry Tutoring Center:  Run by Towson University, this site posts self-tutorials.
• The Chembalancer:  Practice balancing equations with the amazing Chembalancer!
• General Chemistry Online:  Some miscellaneous links that you may find useful.  This dude seems like one heck of a nice guy, incidentally.
