It may take between three and six months to prepare for the exam and get the desired scores. However, if you don't have much preparation time left, a 2-month GRE study plan may also work for you, but it needs to be consistent. Therefore, you have made the fundamental decision to tackle the GRE with just 60 days until you take the exam. While two months isn't a lot of time, it's more than enough for you to learn, practice comfortably, and review all the GRE material.
If you test too far, there will be a greater chance of exhaustion and stress. Let's see what a 2-month curriculum should look like. 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. In fact, most instructors believe that two months is enough for GRE preparation. As mentioned earlier, 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 a few hours a week for GRE.
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). Unlike shorter deadlines, the 2-month GRE curriculum gives you time to discuss each and every topic in the Quantitative Reasoning sections of the GRE so that nothing surprises you on the test itself. 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. There are also one-month GRE curricula, as well as three-month GRE preparation plans, so don't hesitate to check them out as well.
Well, follow the curriculum above to help you prepare GRE in 2 months and achieve a specific GRE score. 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). Factors that change the time you need to fully prepare for GRE include the GRE test scores you need for your target graduate schools, how long you've been out of school, how much you read, your language skills, your experience with standardized tests, and more. If you are aiming for the highest GRE score with two months of preparation, then the online preparation mode would really help you achieve all the requirements under one roof.
My Gre test is in 2 weeks and I have been studying for GRE for 3 months, about 2 hours every other day. To continue with the previous example, if you needed nine weeks to prepare to take the GRE for the first time and you want to budget time to retake it, you will need a total of 13 weeks from when you start studying until you take the GRE for the second time. 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.
