STUDY TIP:  Only study what you DON'T know

Practice tests are a uniquely beneficial tool for the serious student. You can't study everything, nor should you! Practice tests identify the gaps in your knowledge and any weak spots in your understanding. Take the practice test, read the explanations, and then ONLY study the topics you missed.
