This is certainly an important question. After all, the journey of a million miles begins with a single step, so that single step is a pretty big deal! If you're new to CLEPing you may wonder if some tests are better to start with than others.
I would recommend getting your feet wet with one of the easier tests. One of my first CLEPs was Analyzing and Interpreting Literature, and boy, am I grateful! That test was a breeze, and I actually scored an 80 on it! It was a huge moral booster, and that's valuable for kick-starting enthusiasm.
A few other fairly easy ones (in my opinion) would be Introduction to Psychology, Introduction to Sociology, Social Sciences and History, and Humanities. Of course, it's all relative to your background, interests, and education. If English is your second language then the Spanish, French, or German CLEPs could be easy cheesy. History might come naturally for you, so try out College Composition. Maybe you're obsessed with technology (like my little brother) and Information Systems and Computer Applications might be just the thing to get you started.
Just look through the list of subjects and choose one that you're familiar with or interested in. It's much easier to pour yourself into studying something that you care about rather than something you're just wanting to get through.
Once you've passed your first couple of "easy" tests then it might be time for something a little more challenging and outside your comfort zone (College Algebra did that for me!). Work your way up slowly, don't burn out, and study creatively to keep your interest level high. Hold yourself accountable, work hard, and you're almost guaranteed to pass your exams with flying colors!
Happy CLEPing, my fellow non-conformists!
