Spell checking for dummies

I am a college student who is pursing computer science and who also working at a medical device company. You would think that I'm a good speller and at least know how to cross my "t" and dot my "i"s. Well, I apologize but that is not my strong suit. I am a terrible speller. I think some of my old post may show that. How do I handle this? I rely a lot on spell check but I have found out that in Gmail, my browser, and even Microsoft Office, all give me different results for each misspelled word. Many times I have not been able to correct my misspelled word. I rely on another tool. This tool has access to any of the data on the information superhighway or Internet. Google! To find the correct spelling I copy and paste my misspelled word into Google and out pops out the correct word. In addition, this shows you how powerful Google is.
