Reach Higher (started by Michelle Obama) and Collegewise (private college counseling company) created a step by step guide filled with tips for the Common Application. You can download your own copy by filling out the form on the website.
Lots of great tips about each section of the application, tips on essays, answers to common questions (do you have to fill out the additional information section?) and more. Go to : http://go.collegewise.com/collegewise-reach-higher-guide-to-the-common-application to download a free copy. Note, there are tutorials throughout the Common Application and also a very responsive help service. When in doubt check and ask! Don't assume you know how to fill something out if you are not sure! https://www.commonapp.org/help-center
