A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
A few months ago I did a detailed Comparison of Excel 2010 v. Excel 2013. I noticed hundreds of differences between the two versions. I would expect the differences between Excel 2010 v. Excel 2013 to be over 1000 differences. Some of the differences are very subtle, such as the change of an icon, or the change to "help desk displayed upon hover over an icon". I think it is a good idea to have the version of Excel be the same as the class. As far as both versions on the same computer, Microsoft generally supports dual installs of MS Excel versions. For example, I have seen many computers that have both Excel 2010 and 2003 on them, and this works for the most part (the main exception being the need to configure between using Office 2003 or 2010). However, I think it is better to have only one version of Office on a computer, it at all possible (for example, all Office 2007 or all Office 2010). One possible issue with trying to put Excel 2010 and 2013 on the same computer, might be due to 32 bit vs. 64 bit software. I don't think it is possible to install both 32-bit Office 2010 and 64-bit Office 2013 onto the same computer (that is what I remember about this - perhaps someone might post on this with a link to verify this - this was my conclusion due to my personal experience, with very limited testing). I suppose you could try your dual installation of Office 2010 and 2013, and see if it works (might be best to set a restore point before doing so, in case you need to back out the installation). One other idea, you might find it cheaper, and less trouble, to just keep your Office 2013 software, and find a class on Office 2013. There is lots of free training on Office 2013 available via the internet. However, most of that would not really be a "class" but more of a self-study training. Here is one site I would recommend with free Excel 2013 training:
