FAQ
How do you ensure your practice tests are "hyper-realistic" and match the test-day difficulty?
Our 10 practice tests are meticulously designed to mirror the actual GRE's, and are continuously updated and calibrated by GRE experts to ensure the difficulty level and questions content precisely reflect the challenge you'll face on test day.
What makes your vocabulary list "High-Impact" compared to other prep apps?
We don't rely on generic word lists. Our High-Impact Vocabulary is a curated set of words that have been statistically identified as being tested multiple times on past official GRE exams. By focusing on these frequently recurring words, you maximize your vocabulary study time and preparation efficiency.
Can I create custom practice sessions, or am I limited to the full-length tests?
Absolutely. In addition to the 10 full-length practice tests, you can utilize our Targeted Practice feature to create custom practice sets. You can filter by specific topic (e.g., Number Properties, Sentence Equivalence) and choose the difficulty level you want to focus on (e.g., Easy, Medium, Hard).
Does the app provide detailed analytics or explanations for missed questions?
Yes, comprehensive analytics and detailed explanations are a core feature. After every practice test or set, you receive an in-depth performance report showing your strengths and weaknesses by topic, along with clear, step-by-step explanations for every question—especially those you got wrong—to ensure you understand the underlying concepts.
Is the app subscription-based, and what is included in the full access?
The app requires a single 12-month subscription. Full access includes all 10 hyper-realistic practice tests, the complete High-Impact Vocabulary list, unlimited use of the topic and difficulty-based practice sets, and full access to performance analytics and detailed answer explanations.
