If you forget your APA Manual at home, look up the Zondervan copies.
Most Library tools have the capability of creating an APA citation immediately. Look around for icons or the word "Cite" in each tool.
These tools easily create citations for you.
Zotero should become your new best friend. It captures all the citations you identify and allows you to organize them into folders, so that you can work on one project for one course at a time.
In seconds, it will create a list of references that will hopefully require minimal modifications to be 100% APA compliant.
Please Do Not overlook Zotero. Ask Lana Wilson, Research Librarian, for more information and help getting your Zotero account set up.
