When you open the second link that Hunter posted, you may want to print it out..
You will learn the whole fret board... There are tips on how to locating the frets that you will eventually learn..
It sounds like you may have skipped ahead on your tutorial.. It's been awhile since I have gone through fundamentals 1..
If you look at the diagram on the second link you will see that E-F and B-C have no sharps/flats...This is carried out along the rest of the fret board..
One tip I may sugest is to learn how to use the search tool..also the history and bookmarks.. they all can save you a lot of time.. Also like Hunter mentioned is use the web...
Don't forget you can ask question to the instructor who doing the tutorial you are working on.. Go to "Full Access Subscriber Forums " and click on that instructor..
I hope this helps you out..
Good luck and happy playing...
