Like the Math Add-In for Word and OneNote, this is an awesome tool for Chemistry and Biology students. You can really drive your Chemistry Grader nuts with your great looking homework and save time. The downside is that you may need to memorize more stuff since you won’t be spending as much time making your papers look neat.
The installation from Codeplex, is simple (http://chem4word.codeplex.com/) and fast. Once you get the installation completed you can do things like the following. Since I have no idea how to anything chemical, I just slapped down the first molecule in the library.
Give it a shot, looks good!
