The Verdict: A Breath of Fresh Air
Achievable feels different from other test prep platforms. While competitors feel like “school,” Achievable feels like a modern app (think Duolingo meets a textbook).
It is particularly good for students who:
- Hate dry textbooks: The content is written in a conversational, easy-to-understand style.
- Need endless math practice: The “infinite” question generator is a game-changer.
The “Infinite” Quant Generator
This is Achievable’s killer feature. Most courses have a static bank of 1,000 or 2,000 questions. Once you do them, you memorize the answers. Achievable uses templates.
- Template: “Train A leaves at [X] speed…”
- The System: Randomizes [X], [Y], and [Z] every time you see the question.
This means you can practice the concept of “Rate/Time/Distance” 50 times and never see the exact same numbers twice. It forces you to learn the math, not the question.
Adaptive Learning
Achievable uses a spaced-repetition algorithm similar to Anki. It tracks exactly when you are about to forget a concept and serves you a review question at that precise moment. This efficiency cuts down study time significantly.
The Textbook
The course is primarily text-based (with some videos). However, the text is excellent. It avoids the dense, academic jargon found in official ETS materials and explains concepts in plain English.
Final Thoughts
If you are a visual learner who needs hours of video lectures, Magoosh or GregMat might be better. But if you want a clean, efficient, and modern way to master GRE Quant, Achievable is a fantastic choice at a great price point ($199/year).
