Logic is like math. If you did math, you can do logic. Like the subject of math, I want to spread the subject of logic out over the school ages of thirteen through eighteen. Logic is best learned in a dialog format. As you learn in a group, you can help each other grasp logic concepts which are hard to understand.
Discussions help facilitate better understanding of how logic connects with real life.
I recommend making a lifelong logic notebook. This will aid you in remembering what you have learned in logic, and it will serve as a reference tool. See Learning Logic at Home for an explanation of how to make this notebook. Also, put some variety in your logic course. Use web pages and listen to audio tapes.
