Looking at professional certifications? I've discovered that community colleges near me offer Adobe, Microsoft and CompTIA certification exams free of charge! You might find an academic testing center near you that does the same or offers a great discount. Considering these exams usually cost $150-200 when administered by private testing centers? Woot!
