A good place to start https://www.youtube.com/user/ExcelIsFun

Hello,

I was in the same situation 8 months ago, and now i am better than anyone in my class. A good place to start is the "can do" mind set. Excel has less limitation than most people have use for it. Anytime when you want to do something in excel, just remember whenever there is a question, there is always an answer in excel!! Go to Google; ask the right question to find your answer. If you don't know how to ask the question or phrase it, start with what you want to do. For example, i didn't know how to make excel give me the week when i give it a date. I went on Google and search, how do i know what week it is when i have a date in excel", and then the answer will come up. Carefully look through the first few websites, and pay attention to how people phrase the question. Remember; whenever you have a question, someone else must have it before, if there is a question, there is an answer. I guess my quick 2 cents would be, learn how to ask questions on Google.
