While most prep courses and teachers will help to a degree, there is only so much you can expect from a one size fits all approach. Since each person is unique, a tailored approach combining the individual attention of a private tutor with self-study will get you much better results.
Prepare With Proper Question Modules
GMAT private tutor from ‘Gmat Instructor’ can devote themselves entirely to their student rather than spreading their attention across a larger class. Together the private tutor and student can decide how much time to devote to each topic and customize a strategy to achieve their target score. They can help you with the basics and then go beyond and cover every scenario one is likely to encounter. Also covered will be the types of questions, how to manage one's time well and how to handle tricky questions.
Cover Courses Precisely
You will find that the slightly greater cost of having your private tutor is well worth it. A good private tutor is more than simply a subject matter expert but instead an expert on the GMAT in its entirety. Prep classes will appeal to both those that are weak on the basics as well as those who lack the motivation to work well all on their own. Prep classes however can't ensure that you will do the homework after class and often GMAT books are just as good or even better for covering the basics.
If you ever have trouble with a particular area and need to go over it again then this is much easier to do with a GMAT private tutor online than in a large class format. And because you will be working with the same tutor all the time rather than possibly switching instructors as you might in a larger class, your tutor can get to know you and thus can quickly work with you to figure out what needs to be adjusted.
