For general technical questions, post them in the appropriate technical forum (start the thread by filling out the form at the top of that forum) and include links to your reading that you've been doing and ask questions about that reading. In some of the technical forums the thread title will include a "prefix" that you can set to "High School", "Undergraduate, or "Graduate" for the level that you would like the replies to be.
For schoolwork-related problems (even for self-study), post in the Homework Help forums and fill out the Template that you are provided there when starting a new schoolwork thread. That includes the Problem Statement, the Relevant Equations, and your Attempt at the Solution. Always show your work on the problem so that we can then provide tutorial help.
The Homework Statement is where you list the problem word-for-word as it is given to you. You can also upload a PDF or JPEG image of the problem if that helps, but it's usually required that you type the problem in as well. The Relevant Equations section is to help you think about and list the equations and formulas and concepts that may be helpful in working the problem. You then show your work in the section below (the main body of the thread start).
