Taking mock tests makes you aware of the format, content, and types of questions supposed to be asked on the GRE. However, it is not just enough to take a single mock test; you should rather take several mock tests during the course of your preparation so that you are able to evaluate your progress and are ready to take corrective actions wherever necessary.
When you take a mock test it is very important that you analyze your performance on the test. You should particularly focus on the questions you got wrong and figure out what concepts you need to learn or what modifications you should make in your approach so that you do not commit such mistakes in future. At times, it is also necessary to focus on the questions you got right but took a long time to solve. Was there an easier or shorter way to solve the question?
Some of the benefits of taking mock tests are:
Studying while you are still in college gives you the flexibility to reach out to your career center. The availability of unlimited resources gives you an opportunity to approach your seniors for guidance. As they are the ones who have recently experienced the test and can share their experience of taking the test.
Remember to study
Taking mock tests makes you remember how to study; you are habituated to being in class, grasp information and learn to study for your exam. Preparing for mock tests helps you to prepare for the exams well helping you to maintain a distance.
Approaching a flexible schedule
If you are a working professional then finding time to study regularly can be a bit difficult. You have to plan your day well to get some time to study; either you can choose to wake up early to study or to study late at night. You can plan your study as per your need and can choose your own schedule.
Well, the best part is you have an excuse! If you have not performed well you can take it all again.
