Summarize this article in one sentence.
The day after your class, review your notes. If you wrote them by hand, make sure you can read your writing. If not, correct it. It is easier to correct poor penmanship earlier than after you have forgotten what you have written. Quiz yourself on any new key terms. Use highlighters, colored pens, pencils, and sticky notes to highlight important points. Look at the units of measurement for each axis. What is the relationship between the axes? What concept is the graph trying to explain (e.g. supply and demand curves)? Why do the lines slope in the directions they do? Although you likely are busy, aim to get your homework done in advance. This way, if you have questions, you can ask your professor or teaching assistant (TA) before your homework is due. If you complete your homework at the last minute, do not expect your TA to email you back at 3 a.m. When doing your assigned reading, create questions before you read based on the main concepts you are discussing in class or the theme the reading should address. Read while seeking answers to those questions. By reviewing your notes, you are inadvertently studying for future exams. Continue this process by reviewing graded homework assignments when receiving them. Ask your teachers about any confusion you have regarding answers that you did not get right. If your teachers do not discuss the test format, ask. Request information on what types of questions will be ask and how many points will be allotted to each section. Bring together the main ideas from each homework assignment, quiz, or paper. Explain each concept in writing. Share your guide with a classmate to check whether your understandings of the material are the same.  Define the top five or six key terms per chapter. Write down the key ideas and draw the most essential graph of each chapter. Give examples of a numerical problem and an algebraic problem. Use different amounts and numbers than the examples given in class. Write your own exam questions and practice answering them.  Make flashcards for vocabulary terms. Hire a tutor. If you are having trouble understanding economics, consider hiring a tutor for extra individual help. Your professor and TAs have office hours: use them. If you have any questions, bring them to office hours. Attending office hours is a good way to build a professional relationship with your instructors as well. Perhaps you would like to develop your own economics research project. Your instructor is more likely to mentor you if he knows you. Do not expect your professors to be available 24/7 via email or phone. Office hours exist for a reason and email does not supplant the function of office hours. When studying for a difficult exam or doing a tedious homework assignment, remember why you are studying economics. Perhaps you want to work for the National Economic Council at the White House. Maybe you want to be a college professor yourself some day. Having a list near your desk of what you want to achieve with your economic knowledge will help you stay motivated.

Summary:
Review your notes after class. Analyze graphs thoroughly. Complete homework assignments early. Study for exams gradually. Create a study guide. Visit office hours. Keep your goals in mind.
