Official Sources (Most Reliable):
* ETS (Educational Testing Service): This is the organization that creates and administers the GRE. Their website offers official practice materials, including a PowerPrep Plus online practice test which is highly recommended. This is the closest you'll get to the real thing. While there's a cost involved, it's a worthwhile investment.
Free Resources:
* Manhattan Prep's GRE Practice Tests: While Manhattan Prep offers paid courses and materials, they also provide some free practice questions and a limited number of free practice tests on their website.
* Magooosh: Offers a free GRE practice test and other free resources, but their comprehensive prep materials are paid.
* Kaplan: Often provides free practice questions and sometimes free practice tests, though their full-length tests tend to be part of paid packages.
* Khan Academy: Offers some free GRE prep materials, including practice questions. However, the range of practice tests may be limited compared to other options.
Paid Resources (Offer more comprehensive practice):
* Manhattan Prep: Offers comprehensive GRE prep courses and a substantial number of practice tests, considered by many to be high-quality.
* Kaplan: Another well-known test prep company with various GRE prep options, including practice tests and courses.
* Magooosh: Their paid subscription offers a more extensive set of practice tests and video lessons.
* Magoosh: Offers several practice tests as part of their subscription.
* Princeton Review: Similar to Kaplan and Manhattan Prep, they offer paid GRE prep courses and practice tests.
Things to consider when choosing:
* Number of practice tests: How many full-length tests do you want access to?
* Question types: Ensure the practice test covers all question types on the actual GRE.
* Detailed explanations: Are answers explained thoroughly to help you understand your mistakes?
* Adaptive practice: Some platforms offer adaptive tests, simulating the actual GRE's adaptive nature.
* Cost: Free options are readily available, but paid options usually offer more comprehensive materials.
I strongly recommend using at least one official ETS PowerPrep Plus practice test to get a feel for the actual exam format and difficulty. Supplement this with other practice tests from reputable sources like Manhattan Prep or Kaplan to improve your score.
