Here you can see how Target Test Prep and Achievable match up head-to-head in a battle for the Best GRE Test Prep Companies in 2025.
Target Test Prep takes a smart, personalized approach to GRE prep, offering data-driven tools, AI-powered analytics, and thousands of practice questions to help you target exactly where you need to improve. Whether you want to go solo, join live classes, or work one-on-one with a tutor, TTP gives you a well-structured path toward your best GRE score. It's not the cheapest option, but it's one of the most thorough.
Achievable is a quiz-based GRE prep platform that's best for fast-paced, independent learners. You get adaptive learning, unlimited practice, and instant AI essay feedback - but no full-length tests, expert support, or tutoring. It's an efficient tool, but a bit light if you need anything beyond the basics. Still, at $199 for a full year of access, Achievable earns its better-than-average rating from us on affordability alone.
If grad school is on your radar, the GRE might be, too. The Graduate Record Examination is a standardized test used by many graduate and business schools as part of their admissions process. And while more programs are going test-optional, a strong GRE score can still work in your favor - especially if you're trying to offset a lower GPA, win merit-based funding, or prove you're ready for an academically intense program. Whether you're eyeing a master's degree, a Ph.D., or even a specialized MBA, the GRE gives schools one more way to compare applicants - and offers you one more opportunity to stand out.
The GRE is divided into three main sections: Verbal Reasoning, Quantitative Reasoning, and Analytical Writing. You'll also see an unscored or research section, which doesn't count toward your score but is used by ETS (the test-maker) to try out future questions. While that part is unpredictable, the rest of the test is very structured, and that's where GRE prep services can make a big difference. If it's been a while since you tackled geometry proofs or vocabulary in context, you're not the only one - and you don't have to go it alone, either.
GRE prep courses, tutoring, and study platforms come in all shapes and sizes. You'll find intensive programs that run like college classes, apps that help you build skills on the go, and self-paced courses with video lessons, quizzes, and full-length practice exams. Some platforms use adaptive learning technology to target your weak spots, while others give you a weekly schedule to follow. No matter what your learning style or timeline looks like, there's likely a GRE prep service that fits.
If you're someone who learns best with structure and accountability, a live or instructor-led course might be the right move. These kinds of GRE prep platforms offer both in-person and online classes with expert instructors, homework assignments, and regular check-ins to keep you on track. Prefer to study on your own time? Look for self-paced programs that you can access anytime, anywhere. Most of the time, you'll still get video lessons, practice questions, and score analytics - you just don't have to show up to class. And if you're aiming for a top-tier score or trying to overcome a particular weak area, private tutoring may be worth the investment. Some companies offer one-on-one sessions either as a standalone service or as part of a course bundle. It costs more, but it's often the fastest way to see improvement.
