The best way to prepare for a test is to familiarize yourself with the assessment format. A practice test can definitely help you prepare for the real one. Practice tests work by allowing you to diagnose any major weaknesses you have with the subject matter, and they also provide an opportunity to measure improvement with each test you take.
Taking practice tests for sentence correction is a great way to gradually improve your skill. After taking a practice test, it is important that you do not get discouraged by the number of items that you answered incorrectly. If you get an item wrong, note the difference between the right answer and yours. Read the explanation that comes with the practice test and determine why you got that particular test question wrong. Also, look for recurring mistakes that you seem to be making. For example, if you notice that you consistently miss questions pertaining to verb tense, review any notes or information that you have on that subject. Take note, too, of questions that took a long time to answer, even if you did get them right.
When deciding how many practice tests you will need to take, remember that quality is better than quantity. For example, it is better to take three practice tests and carefully scrutinize your answers than to take seven and simply hope that your score goes up with each mock test. What is important to remember is that you should not take too long between practice tests. The longer the amount of time you take between exercises, the less able you will be to build upon what you have learned from the previous test.
When you find yourself preparing for a test, it is important that you develop a realistic study schedule. Look at your schedule and decide when the best time is for you to study. If you have Thursday evenings free, for instance, that would be a good time to prepare. While it is important to be motivated and to work hard, do not put too much pressure on yourself. A suggestion would be to take your practice exam, score it, then take a break to have some free time for yourself. When you return to your study session, try to focus on the test question explanations for 30 to 45 minutes at a time, taking reasonable breaks so that you do not become too overwhelmed with information on grammatical content. If you find yourself becoming distracted, it is easier to refocus yourself if you know that you have a ten-minute break coming up. Study relatively close to the test date without falling into the trap of cramming the night before. It doesn’t make sense to study in January for a March test date with no review in between.
How many hours you practice a day depends on the difficulty of the test and your knowledge base. Remember though, that your last practice test should not be taken later than 48 hours before you take the real test; you will need to allow yourself time for review and rest. It is a good rule of thumb to quickly review right before going to bed or before a nap, to help your brain convert the information from your short-term to your long-term memory.
