Test your mental acuity in a five-category quiz: thinking, memorization, computation, analysis, and identification. Work your computing abilities by comparing stacks of coins to find the higher value! Bulk up your analysis skills by quickly counting a huge stack of books! Each exercise takes less than a minute to complete. After you take the quiz, you'll get the weight of your brain, areas of strength and weakness -- and, most importantly, which career is best suited for you. Don't worry, it's all in fun.
