In one sentence, describe what the following article is about:

The PSAT exam is meant to test you on knowledge that you should have already learned in class. A great way to refresh your memory is to read through your notes from various classes – especially Math and English/Literature courses. Try to review specific concepts and make sure you understand everything you read in your notes. If you have questions about specific topics, ask your teacher if they have time to review the concept with you before the exam. Reading books has been proven to increase your knowledge, creativity, and critical thinking skills, all of which are helpful test-taking tools. It’s an activity that increases empathy and passion, and allows you to understand the world around you more completely.  Ask a teacher or librarian for recommendations of books if you have trouble figuring out where to start! Be sure to read all of the assigned reading in your classes, along with other reading materials – like newspapers, magazines, and online articles. Writing down your thoughts and experiences in a journal or diary is a great way to practice your writing skills, which you’ll need to do if you want to do well on the PSAT exam.  Keeping a daily journal can also help you track your progress. You can look back over your past entries to see how you’ve improved over time. You might also want to ask a trusted teacher or friend to give you feedback on your writing. Though, you may want to be careful about avoiding too-personal topics in your journal if you plan on doing this.

Summary:
Review your class notes. Read books you enjoy. Start journaling.
