We are constantly adding to this vocabulary list and rebinning as we collect additional data. Levelizing is built on a formula derived from frequency and dispersion analysis from multiple corpora, and on over 30 years of tests further moderated by our vocabulary experts. See our word gallery to understand how each word is taught and our question gallery to see our reinforcement questions.
Note that when certain words like abandon are binned at what seems to be a higher level than expected we are teaching an alternate meaning for a polysemous word, or the word is easily confused, as in the case of enormity.
