(Online)

 

- This is just optional, if you want to check the progress on your score  

- Buy it from www.mba.com. Practice 1 set every 1-2 weeks to get an estimated GMAT score. This is a reliable source. We don’t recommend practicing with other sources because their questions tend to be outdated and their estimated score tends to be higher, thus unrealistic and unreliable.

 


[2. Tips for students who don’t have enough time to study]
 

If you really cannot find enough time to study and have only 2-3 weeks at maximum, we suggest you just focus on DS. DS is a quick-win compared to PS. You can follow above steps but study DS sections only. If your current score is at Q43-46, mastering the Variable Approach of DS only will still get you a score of 49. If you have some time left to study PS after mastering DS, please study PS using the guidance above.
 

[3. Tips for quick improvement without studying all materials] 
 

Please remember that key questions for GMAT Math are “Integer, Statistics, Probability, Inequality and Absolute Value”, which account for 80% of the GMAT exam. Among 5 chapters, Integer and Statistics are most frequent and most important compare to the other 3 chapters. Please try to master and focus on these 5 chapters. If you can find more time, you can further study “Geometry” and “Equation”
 

[4. Other useful tips]
 

Study Math Revolution only - We suggest you NOT study outside sources' materials from the source outside Math Revolution. Their questions tend to be “out-of-date”, and teach “general math skills” that takes very long to improve and are often not related to GMAT math. GMAT math requires logical skills and basic math skills related to GMAT math. We teach “GMAT math”, not “general math”. We also use “Up-to-date” questions that tend to appear in the actual exam.


“Math Secret” video - In the "on-demand" course, you will see "Math Secret" videos. This section shows good examples of each secret solution type. You can refer back to them anytime.
 

Theory Flash Card - We offer Theory Flashcard which explains key concepts of the Variable Approach and IVY Approach. You can download it from “My Class → Summary”. Please print and refer to it whenever needed. 


Two Study Options - Under "Study Room", you can practice questions, then watch the video solutions or read written solutions with screenshots of the videos. You can also watch videos directly without practicing questions. We recommend that you watch the videos entirely, especially those for DS+PS (Core theory), since our approach is very unique and different from conventional approaches. Please note that we do not provide practice options for "Math Review" and "Official Guide". 
 

Screenshot of video explanation- Under "My Class→Study Room", "the end-shot of each video" can be printed for a quick review of the entire writing on the board. You can study this when you do not have enough time to watch the entire video. 
 

Open Questions - If you have “any questions regarding math videos”, please post your questions at the Q&A of each video in the "Study Room" under "My Class". We operate "Open Forum" for Q&A on all our videos so everyone can benefit from open Q&A’s. 
 

Video speed control : You can control the speed of our lecture videos from 0.5 times to 2.0 times the original speed depending on your skills and comfort level.

 


 

Q6. What differentiates Math Revolution?

Forget conventional ways of solving GMAT Math problems.

For 18 years, the one-and-only WORLD'S FIRST Variable Approach for DS and IVY Approach for PS allows anyone to easily solve GMAT math questions. GMAT math is "logic". 
These methods have helped students dramatically reduce their time spent per question with speed and accuracy regardless of their math skills.
In fact, students who have studied with Math Revolution lectures often report having 10 minutes to spare before the exam ends.

While some students hit a score of 45 at minimum, 90% of our students hit a score of 49 and above. The remarkable and guaranteed improvements in scores are what differentiate Math Revolution from all other GMAT prep courses.  

Q7. How long will it take to achieve a score between Q49-51 with Math Revolution?

We do not make promises that we can’t keep. However, results may vary depending on your current math skills and the number of hours you have available to study per day.

Assuming you study 2-3 hours per day and our video lesson hours are 55-75 hours at maximum, you may consider repeating the course to fully master it.

☞ Students with a score of 45-49 ==> 1 month 
 Students with a score of 35-44 ==> 1-2 months.

 Students with a score of less than 34 ==> 2-4 months.  

Q8. How to improve scores from Q25-34 to Q45-49

Many students scoring at this level are very weak with math basics. The major difference between Q20’s-34 and Q35-42 is basic math skills. 


Please always remember the principle of "Slow, Hand, Detail"
​.
 

  • ​☞​ Solve "slowly" when you study and practice.

  • ​☞​ ​Solve the problems by "hand" as a rule.  Understanding how the problems are solved in videos is very different from actually ​ solving them on paper yourself. So, practice by solving the problems by hand-writing them is very important after you have studied with the videos.When you solve them, write a "detailed" calculation process without skipping any steps. This is also important.

    ☞ ​If you don’t follow the above advice, you will have a difficult time improving your GMAT math skills and scores. If you are not strong in basic math skills, your PS won’t be good. If your PS isn't good, you will have a difficult time in establishing equations in DS. So, your DS would not be good either. 

 



How to score between Q45-49
 

  • ​☞ Enroll in “All-In-One 51” for 2-3 months. Sorry, a 1-month course is too short to improve.

  • ☞ Follow the "Slow, Hand, Detail" advice mentioned above. This is a very important principle and habit that you have to keep in mind at all times.

  •  ​Build your math basics with our "Math Review" (5-hour lesson). These videos are for reviewing basic math including arithmetic, algebra, geometry and word problems.  At your level, you need to go over these videos twice. We are sure that you can strengthen your basic math skills. However, we suggest you refer to these videos any time you need to refresh and master the basics.

    In addition, we have free video lessons for math basics. Please refer to “Must-Know Formula” and “Must-Know Math Basics”. Click
    These videos can help but they are not comprehensive enough to fully strengthen your basic math skills. “Math Review” videos in our paid course will provide you with more confidence in mastering math basics.

  • ☞ Then, you can move on to our unique approaches to solve any kind of GMAT math questions. DS is quite easy and a quick win. DS is our biggest strength. If you learn the Variable Approach for DS which saves time significantly, is very unique, and very different from conventional ways of solving equations, you can easily achieve a score of 45 and above. Just trust and learn the Variable Approach. Basic math skills are necessary, but more importantly, a command of logical skills is required.

  • ☞ Your study order is Math Review --> DS+PS --> Introductory --> Basic --> OG --> Advanced --> Practice Test --> Special Question Pack.

  • ☞ Our online course is very comprehensive, making it easier for you to study on your own. You may also ask as many questions as possible via online. However, you may consider private tutoring: $600 for a total of 6 hours, the best rate for the best quality in the market.    

 ​ 

Q9. How to improve scores from Q35-44 to Q49-51

If you are stuck at 30's-low 40's, your issue would be PS and your basic math skills are probably shaky. You most likely make unnecessary mistakes in basic-to-middle level questions and you cannot move up to advanced level questions in CAT's.
 

Many students at this level of scoring seem to solve the questions with their eyes, meaning they easily understand what is taught but they don't actually understand the entire process of calculation when writing it outIf they encounter such questions, they tend not to solve them. 

If this sounds like you, please always remember the principle of "Slow, Hand, Detail".
​ 

  • ​☞ Solve "slowly" when you study and practice.

  • ☞ Solve the problems by "hand" as a rule.  Understanding how the problems are solved in videos is very different from actually solving them yourself. So, practice by solving the problems by hand-writing them is very important after you have studied with the videos.

  • ​​☞ When you solve them, write a "detailed" calculation process without skipping any steps. This is also important.  

If you do not follow the above advice, but think you know it well, you cannot solve the problems properly. ​ 
If you are not strong in basic math skills, your PS won’t be good. If your PS isn't good, you will have a difficult time in establishing equations in DS. So, your DS will not be good either. 
 
 

How to score between Q49-51
 

  •  ​Enroll in “All-In-One 51” for 1-3 months.

  •  Flow the "Slow, Hand, Detail" mentioned above. This is a very important principle and habit that you have to keep in mind at all times. 

  •  Build your math basics with our "Math Review" (5-hour lesson). These videos are for reviewing basic math including arithmetic, algebra, geometry and word problems.  As long as you cover these videos, we are sure that you can strengthen math basics. 
    In addition, we have free video lessons for math basics. Please refer to “Must-Know Formula” and “Must-Know Math Basics”. Click 
    These videos can help but they are not comprehensive enough to fully strengthen your basic math skills. “Math Review” videos in our paid course will provide you with more confidence in mastering math basics. 

  • ​​ Once confident with your basic math skills, you can move on to our unique approaches to solving any kind of GMAT math questions. DS is quite easy and it is a quick win. DS is our biggest strength. If you learn the Variable Approach for DS which saves time significantly, is very unique, and very different from conventional ways of solving equations, you can easily achieve a score of 49 and above. Just trust and learn the Variable Approach. Basic math skills are necessary, but more importantly, a command of logical skills is required.

Q10. How to improve score from Q45-49 to Q50-51

Our experience is that many students at this score level are good at both DS and PS.


Their issues 
 
 

  •  "Time management" is pressuring them to solve the questions on time.  

  •  They know so-called 700-level questions, but they tend to practice out-of-date questions and don't know the types of questions determining a score of 49-51. 

 

How to score Q50-51 in a short-period of time

 

  •  Enroll in the “Short-Cut 51” course. 

  •  Focus on DS. DS is a quick win. You may save PS for later. If you learn the Variable Approach for DS which saves time significantly, is very unique, and very different from conventional ways of solving questions, you can easily achieve 49 and above. Just trust and master the Variable Approach.

  •  Additionally, you will have to learn Common Mistake Types (CMT) 3 and 4 that determine a score of 49-51. You will encounter 4-5 CMT questions in the actual exam. If you get half of them correct, you will reach a score of 49. If you get 1-2 of them wrong, you will achieve a 50. If you get all of them correct, you will hit 51. These questions usually take 4-5 minutes to solve through conventional methods. After learning CMT types 3 and 4, such questions will take you only about 2 minutes per question. 

  • ​ Also, focus on 5 key types of problems: integer, statistics, inequality, probability, and absolute value which account for 80% of the GMAT exam. 

  • ​ If your PS skills are good, but not strong, you can improve your PS skills significantly. It won't take long. Our IVY Approach for PS provides you with many techniques and tips to solve PS easily, with speed and accuracy.  

  

Q11. I am not strong in math. How can I start from the very beginning?

You are at the score level of Q25-30. 

Please refer to FAQ Q5 ➔ “How to improve from Q25-34 to Q45-49” 

Q12. I only have 2-3 weeks left. Can I still improve my score?

It is not easy, but possible. Purchase either Short-Cut 51 or All-In-One 51 course, and focus and master solely the DS section. If you study at least 3 hours a day, you can improve your score in just about 2 weeks. Variable Approach for DS is a quick win compared to IVY Approach, a method for PS. Also, a majority of questions that determine a score of 50-51 are DS. If you focus on DS for 2 weeks, you can improve your score by 3-5 points. In essence, hitting a score of 49 is doable by studying and mastering DS only. However, you should have good math basics. 


  • ​☞ Focus on DS. DS is a quick win. You may save PS for later. If you learn the Variable Approach for DS which saves time significantly, is very unique, and very different from conventional ways of solving equations, you can easily score 49 and above. Just trust and master the Variable Approach.

Q17. How does “Daily Quiz” work?

Daily Quiz is just newly launched. We have successfully executed this program since 2 years ago.

 

  • ​ We send 5 questions and solutions every day from Monday to Friday for 8 weeks. 
  • ☞ Please spare 10-15 minutes and solve them every day after lunch, free time or break time. 
  • ☞ ​We offer 2 options ==> 1-month ($29) or 2-month ($49) 

You will experience significant math improvement by daily practice. Math is all about "habit". 

Did you know that rather than studying intensely for a short period of time, spending a certain amount of time each day to study is much more effective for improving math skills?
One tip for Daily Quiz is that after you learn how to solve the questions that you once could not solve, you should re-write the solutions again by hand. 
Learning solutions on paper does not mean that you can actually solve them when you encounter similar questions. 
Rewriting the solutions you learned by hand will reinforce what you learned and confirm that you completely understand these types of questions and solutions.

The video course is very comprehensive for mastering GMAT Math. The Daily quiz is to help motivate students to practice them every day and to keep reminding them of their of MBA dreams.
