[2. Tips for students who don’t have enough time to study]
If you really cannot find enough time to study and have only 23 weeks at maximum, we suggest you just focus on DS. DS is a quickwin compared to PS. You can follow above steps but study DS sections only. If your current score is at Q4346, 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 “outofdate”, 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 “Uptodate” questions that tend to appear in the actual exam.
☞ “Math Secret” video  In the "ondemand" 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 endshot 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.
Forget conventional ways of solving GMAT Math problems.
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.
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.
☞ Students with a score of less than 34 ==> 25 months.
Many students scoring at this level are very weak with math basics. The major difference between Q20’s34 and Q3542 is basic math skills.
Please always remember the principle of "Slow, Hand, Detail".
How to score between Q4549
If you are stuck at 30'slow 40's, your issue would be PS and your basic math skills are probably shaky. You most likely make unnecessary mistakes in basictomiddle 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 out. If they encounter such questions, they tend not to solve them.
If this sounds like you, please always remember the principle of "Slow, Hand, Detail".
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 Q4951
Our experience is that many students at this score level are good at both DS and PS.

How to score Q5051 in a shortperiod of time
You are at the score level of Q2530.
Please refer to FAQ Q6 ➔ “How to improve from Q2534 to Q4549”
It is not easy, but possible. Purchase AllInOne 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 5051 are DS. If you focus on DS for 2 weeks, you can improve your score by 35 points. In essence, hitting a score of 49 is doable by studying and mastering DS only. However, you should have good math basics.

Unlike most of the other test prep companies that do not frequently update their contents, Math Revolution has our own Math Research Institute that regularly conducts a research, updates question banks, and offers the newest types of questions based on surveys we conduct on the actual test takers. You cannot get high scores on the GMAT Math if you only study with outdated questions. In fact, many mock tests and questions on CAT that are easily available everywhere for purchase also contain the outdated questions. This is why so many students experience huge differences between their mock test scores and their actual scores. Hence, it is very important that you understand the trend on the types of questions used on the exam. Please Click to the article featured in GMAT Club. This article is very useful for anyone who wants to know the most current trend for the GMAT Math questions.
