Frequently Asked Questions
What is the difference between monthly and lifetime?
Monthly ($20/mo) suits a short exam sprint — cancel anytime. Lifetime ($49, one payment) unlocks every course forever, including future ones, and works out cheaper the moment you study for more than a couple of months.
Which courses does Pro include?
All of them: Root Mastery Basics, the GRE Root Course, the TOEFL Root Course, and every course we add later. One pass, no per-course fees.
Do roots and words cost anything?
No. 16,000+ words, 600+ roots, all vocabulary collections, and articles are free forever — no account required. Pro is only for the courses.
Will I lose my data?
No. Your vocabulary book and mastery data are always yours, free plan or not.
