Hello, I believe you need tutoring to determine your weakest areas.
I believe that the series of tests are important once you got the basics. Even if you are a hard working student, you might be able to memorize the different patterns and improve at some degree in standard tests such as Kaplan, Princenton a so on. However, your weakness will arise once you face completlely new questions in the real test.
I am working in a project to provide online tutoring, you are welcome to contact me
[email protected]I do strongly recommend you NOT to take my test since you need to master the esentials to test your improvements
