As mentioned, what were your practice test scores?
There are three groups of people:
1.
Unlucky - This score considerably less than their practice scores and the nutcase often can retake within two weeks and gain 50 to 100 points by doing zero studying basically.
2. As expected - Those who score exactly the same Or approximately the same score as their practice tests. For this group, it will take effort and serious studying to improve their score. Retaking the test without meaningful changes will not impact the score to the positive.
3. Lucky - they got a score that was at the peak or even above their peak performance. There are many reasons for this such as extra effort or better performance and distress or just luck. I managed to get 10 points above my prep score for example. Retaking for this group may not be lucky next time. I would not recommend Retaking anesthetic can make again meaningful improvements.
PS. It is generally unproductive to take a test hoping to score more than your practice test scores. There are some variations and scores do have inconsistencies and if the real test does have inconsistencies as well, it tends to error on the lower side....
PS. if you’re looking for M7, it’s going to be tricky because their average tends to be 30 points above. They make exceptions and it may be worth giving it a shot but the rest of the application needs to be spotless and strong. There are ways to explain lower scores with optional essays and so on but that implies you have a strong undergraduate GPA. That is higher than the average of 3.5 or 3.6.
Another option could be to go and take the GRE almost cold. Spending a week or two may get you to schools average score and for a US based applicant, that’s good enough. For somebody from Asia, you need six points above average more or less but the trade-off is that there’s not a whole lot of financial aid for Jerry applicants since they are getting somewhat of a discount on their test score
