To achieve a 650+ GMAT score, you must:
1) Learn the concepts and techniques tested on the GMAT (e.g., circle properties, divisibility rules, past perfect tense, equation-solving, etc.)
2) Master GMAT-specific strategies (e.g., testing the answer choices, rephrasing the target question, identifying subjects and verbs in sentences, etc.)
3) Understand the many different ways the test-makers can test your knowledge of each concept
4) Hone your test-taking skills (e.g., endurance, time management, guessing strategies, etc.)
Many students make the mistake of limiting their preparation to item #1 (and perhaps item #2). So, once they fully grasp a concept and successfully answer 1 or 2 related questions, they move on to the next topic.
The problem with this strategy is that the test-makers can take any concept, no matter how simple, and create
dozens of wildly different questions , each requiring a different approach. So, to achieve a great score, you must answer a lot of practice questions
specifically-related to each concept tested on the GMAT.
Given all of this, I recommend a systematic approach, in which you take the time to thoroughly address each topic/concept. So, for each topic/concept, you should:
- Learn the underlying concepts (rules, attributes, notation, etc.)
- Learn the GMAT-specific strategies related to that topic
- Practice dozens of questions, all related to that one topic.
- Don't stop working on that topic until you have mastered it
Then,
and only then , move on to the next topic.
Our free course is specifically designed with this approach in mind. For example, at the bottom of the lesson page on inequalities (
https://www.gmatprepnow.com/module/gmat ... /video/979), you’ll find links to dozens of practice questions that test the specific concepts covered in that video.
Having said that, you can use the same approach with
ANY prep course. To help you fully explore the ins and outs of each topic, you can use GMAT Club's question-tagging tool (
search.php?view=search_tags). This will give you access to tons of
topic-specific practice questions.
Finally, your study plan should include several full-length practice tests. Keep in mind that the GMAT is a test of your math and verbal skills
AND it's a test of your test-taking skills. So, 700-level math/verbal skills, combined with 600-level test-taking skills, will likely result in a score that's closer to 600 than to 700.
I hope that helps.
Cheers,
