You can't prepare for the GRE test. In general, the test is a test of patterns, not facts, so if you want to increase your GRE score, you will need enough time to practice. We suggest you spend 4-12 weeks preparing for the GRE. Taking into account all the points we have mentioned, the preparation of the GRE will take between 4 and 20 weeks.
If you include the mock tests you would have to perform, the preparation time can range from a minimum of 6 weeks to a maximum of 24 weeks. As mentioned above, there is a great deal of variation in the amount of time people choose to prepare for the GRE. However, most people spend between one and three months studying for GRE a few hours a week. This means that the number of studies for GRE could range from approximately eight hours (studying two hours a week for four weeks) to 120 hours (studying ten hours a week for 12 weeks).
This answer depends on your goal scores and how far you are from those scores. In any case, you should not spend less than 2 weeks studying for the GRE and you are likely to achieve diminishing returns after 6 months of study. Ideally, you should spend 1 month to 5 months studying. I received an email from a university asking me to retake a gre test to meet the minimum requirement.
However, it is not as much time as it seems, so this study program requires around 3 hours every day, as well as one day a week that you can spend taking a full practice GRE exam. If you scored 284 for the content and for the strange GRE style, it would be absolutely feasible to see an increase of 15 to 20 points once you have internalized the GRE style and more content. One important thing to remember is that “actual ETS GRE tests are the only truly reliable measure of the score you can get on test day. It's usually pretty easy to know which one (physics programs tend to care much more about the quantitative section, while enlightened programs tend to focus quite heavily on the GRE verbal section), but check with them just to make sure before you devote (or cancel) six months of GRE study that they may not do a difference in your chances of admission.
You'll also cover the 1,000 GRE words included in most GRE vocabulary flashcard packs, and you'll have time to add your own words from supplemental reading. Also, if vocabulary is an area you have set out to improve, plan to carry GRE flashcards (physical cards or a phone app) with you and work on GRE vocabulary throughout the day. If you work with math on a daily basis, you'll likely need less preparation in that area, which can reduce the amount of time you need to efficiently prepare for GRE. This means that you have a slight advantage in GRE versus GMAT, but they are close enough that you can select the test you're most comfortable with (assuming both GRE and GMAT are accepted for the programs you want).
Taking a practice test at the beginning of your GRE preparation is a great way to assess what you need to work on. People can take practice tests, read the different sections of the test, read old school notes, buy and read a GRE prep book or a combination of the above.

Therefore, taking into account the three weeks for schools to receive grades, the person in the example would have to start preparing for the GRE 16 weeks before the first application deadline (9 weeks to prepare for the first exam + 4 weeks to prepare for a new test + 3 weeks for the first test to be schools receive grades).
