Good, but glitchy – Vocabulary Builder by Magoosh Review

This is an amazing way to learn new vocabulary, but on the GRE Intermediate vocab, my progress is never saved. Since you have to pass each level to move on to the new ones, I have to spend 15-20 min catching up again to reach a new level. Otherwise 5/5.
